• B. Custom object as the master" and a standard object as the detail
• C. Custom object as a lookup to a standard object
• D. Custom object as a lookup to a custom object

Correct answer: B

Explanation

Answer B is correct because Salesforce does not allow a custom object to be the master in a master-detail relationship with a standard object as the detail. The other options are valid relationships that Salesforce supports, where standard objects can be used as masters and custom objects can be used as lookups.
