Declarative customizations are the ones that can be done using the point-and-click tools provided by Salesforce, such as Process Builder, Flow Builder, Lightning App Builder, etc. Code customizations are the ones that require writing Apex, Visualforce, or Lightning Web Components. Some of the benefits of using declarative customizations over code are:

• Declarative customizations automatically update with each Salesforce release. This means that whenever Salesforce improves or adds a new feature to its declarative tools, the existing customizations will be compatible and take advantage of the enhancement without any additional effort from the developer1.
• Declarative customizations generally require less maintenance. This is because declarative customizations are easier to create, modify, and debug than code customizations. They also do not require writing test classes or deploying to different environments, which can save time and resources2.

The other two options are not true benefits of declarative customizations over code:

• Declarative customizations do not automatically generate test classes. Test classes are only required for code customizations, and they have to be written manually by the developer. Test classes are used to ensure the quality and functionality of the code, and to meet the code coverage requirement for deployment3.
• Declarative customizations can still generate run time errors. Run time errors are the ones that occur when the application is running, and they can be caused by various factors, such as invalid data, logic errors, or system limits. Declarative customizations are not immune to run time errors, and they have to be handled properly by the developer using error handling techniques.

A validation rule is a formula that evaluates the data in one or more fields and returns a value of true or false. Validation rules verify that the data a user enters in a record meets the standards you specify before the user can save the record. A validation rule can contain a formula or expression that evaluates the data in one or more fields and returns a value of true or false. Validation rules also include an error message to display to the user when the rule returns a value of false after the user attempts to save the record. In this case, a validation rule can be used to prevent users from editing opportunities that have reached the Closed stage by checking the value of the StageName field and displaying an error message if the user tries to save any changes. References: Validation Rules Salesforce Platform Developer 1 Exam Guide, page 6.

VSCode and SFDX CLI are two tools that can be used to run a script that deploys to a sandbox. VSCode is a code editor that supports Salesforce development with the Salesforce Extension Pack1. SFDX CLI is a command-line interface that allows you to perform various tasks related to Salesforce development, such as creating projects, pushing and pulling source code, running tests, and deploying to orgs2. Both tools can be integrated with a version control system and a CI/CD pipeline to automate the deployment process to a sandbox3. Change Sets and Developer Console are not tools that can run a script that deploys to a sandbox. Change Sets are a declarative way of deploying metadata changes from one org to another. Developer Console is an integrated development environment that allows you to edit, debug, and test Apex code and Visualforce pages. Neither of them can execute a custom script that deploys to a sandbox. References: 1: Visual Studio Code - Salesforce Developers (1) 2: Salesforce CLI - Salesforce Developers (2) 3: How to Work with Developer Sandboxes and the Salesforce CLI (1 of 2) | Salesforce Developers Blog (3) : Change Sets - Salesforce Help (4) : Developer Console - Salesforce Help (5)

 The @InvocableMethod annotation is used to identify a method in an Apex class that can be called from a flow, a bot, or an NBA strategy. It is a helpful annotation to provide a seamless admin-friendly way to call the Apex code using simple flows. Invoking Apex from flow is a significant option for providing design patterns that can solve many business problems while also providing great user experience. The other annotations are not suitable for this scenario, as they have different purposes and limitations. For example, the @future annotation is used to execute a method asynchronously, the @RemoteAction annotation is used to expose a method to a Visualforce page, and the @AuraEnabled annotation is used to enable a method to be called from a Lightning web component or an Aura component. References: Annotations, How to Invoke Apex from Flows Using InvocableMethod Annotation, Salesforce Flow
