Answer:
A) the associate may pay the salary and withhold taxes, but the broker must pay commissions.
Explanation:
The sales associate works for the broker and his/her assistant works for him. Therefore the sales associate is responsible for paying the assistant's salary and withhold taxes since he is the employer. But since the assistant will also earn 20 percent of the sales associate's commissions, that should be paid by the broker directly (80% to the sales associate and 20% to the assistant).
