Data Validation Rules and Salesforce Editions

F.

Data validation rules are used to ensure that the data entered into Salesforce fields meet certain criteria. They allow administrators to define custom error messages that display when users try to save records with invalid data.

In Salesforce, data validation rules are available in most editions, with the exception of Contact Manager Edition. Contact Manager is a very basic Salesforce edition that is typically used by small businesses with only a few users. It is designed to be an entry-level edition with limited functionality and features.

Data validation rules are available in Group, Professional, Developer, and Unlimited Editions of Salesforce. Group Edition is designed for small businesses with up to 5 users, and Professional Edition is designed for small to medium-sized businesses with up to 10 users. Developer Edition is a free, fully-featured version of Salesforce that is designed for developers to test and build applications. Unlimited Edition is the most comprehensive edition of Salesforce and includes all of the features and functionality of the other editions.

Therefore, the correct answer to the question is A. Contact Manager, as it is the only edition that does not support data validation rules.
