Answer:
You have to combine the transactions on behalf of a person and transactions made by an individual. Each of the three conductors made a transaction on behalf of A, so all of the transactions get combined in one CTR.
The CTR will have separate Section A entries for A, B and C, there need not be any Section B entries (except for "conducted on own behalf" in Section B on the front), and the total in item 26 is $21,010. All of the account numbers get listed in Part II of the form. Check "multiple transactions" in item 1.
