Answer: The obligation to assert the privilege rests with the COUNSELOR
Explanation: A counselor is a professional that advises people especially on personal problems. In order to be able to advise people effectively, a lot of personal information will be given away by the client to the counselor. Usually it is expected that this remains between the client and the counselor.
If a counselor is asked to provide privileged information about a client, it is solely up to the counselor to oblige.
