What could be the issue?

AW Computers has enabled the feature for Contact to multiple Accounts. A rep is trying to remove the primary Account from a Contact but Is unable to do so. The administrator has already updated

the page layout to no longer require an Account.

What could be the issue?
A . A primary Account relationship Is required on a Contact regardless of the page layout settings.
B . The Contact has Indirect relationships to other Accounts.
C . The Account Contact relationship record needs to be deleted first In order to disassociate Contact from the Account.
D . Private Contacts need to be enabled in Setup.

Answer: A

Explanation:

When Contacts to Multiple Accounts is enabled, a contact must always be associated with a primary account, even if the account field is not required on the page layout. The primary account determines how the contact is shared and how roll-up summary fields calculate values from the contact records. To remove the primary account from a contact, the contact must be deleted or merged with another contact.
