WANNABE_CPA – Here is the answer why not A.
AR-90
Establishing an understanding
The accountant should establish an understanding with management regarding the services to be performed and document that through a written communication with management.
A. The understanding should include the objectives of the engagement, management's responsibilities, the accountant's responsibilities, and the limitations of the engagement.
B. These matters should be communicated in an “engagement letter.”
So the answer why not answer A. is because AR-90 indicates “should be” vs. “Must” in answer A.
