Final answer:
The broker would be committing a license law violation if he were to deposit the check in a personal, business, or joint account.
Step-by-step explanation:
The correct answer is C) escrow.
A listing broker in Minnesota is responsible for handling funds related to a real estate transaction. When the broker receives a commission check from the seller at closing, it should be deposited into an escrow account. An escrow account is a separate account specifically designed to hold funds for safekeeping until a specified event or condition occurs.
By depositing the commission check into a personal, business, or joint account, the broker would be violating license law. This is because the broker has a fiduciary duty to the parties involved in the real estate transaction and must handle the funds in accordance with applicable regulations.
