A developer is trying to access org data from within a test class. Which sObject type requires the test class to have the (seeAllData=true) annotation?

By default, Apex test classes are isolated from organizational data to ensure tests are independent and repeatable. However, some setup and metadata objects function as exceptions and are always accessible without the @isTest(SeeAllData=true) annotation. User, Profile, and RecordType belong to this category of setup objects. The Report sObject, however, is not classified as a globally accessible setup object. Furthermore, because Report records cannot be created using standard Apex Data Manipulation Language (DML) statements, the only way a test class can query and access existing Report records from the organization is by explicitly annotating the test class or test method with @isTest(SeeAllData=true).

A. User: Incorrect because User is a setup object that is automatically visible to test classes without special annotations.
B. RecordType: Incorrect because RecordType is universally accessible in test contexts without requiring the SeeAllData annotation.
D. Profile: Incorrect because Profile is a setup object and is persistently available to unit tests without requiring the SeeAllData annotation.
