Answer: D

Explanation:

A User can have only 1 Profile in Salesforce. A Profile defines the permissions and access settings for a User. A User cannot have multiple Profiles or switch between them. A User can have multiple Permission Sets, which are additional sets of permissions that can be assigned to a User on top of their Profile.
