Correct Answers: A, D, E
A. The master object can be a standard or custom object. ✅ True. You can have either as master.
B. Permissions for the detail record are set independently of the master. ❌ False. Permissions are inherited from the master.
C. Each object can have up to five master-detail relationships. ❌ False. It’s up to 2 master-detail relationships, not 5.
D. Roll-up summaries are supported in master-detail relationships. ✅ True.
E. The owner field on the detail records is the owner of the master record. ✅ True. Detail records don’t have their own owner.

I chose **A, D, E** because they accurately describe master-detail relationships in Salesforce, while **B** and **C** are incorrect due to dependent permissions and the limit of two master-detail relationships per object.
