Final answer:
The bank is guilty of a tying arrangement, which is a violation of antitrust laws.
Step-by-step explanation:
The bank is guilty of a tying arrangement. A tying arrangement occurs when a seller requires a buyer to purchase an additional product or service as a condition of the main purchase. In this case, the bank is requiring the borrower to purchase credit insurance from a specific company in order to obtain the loan. This is considered a violation of antitrust laws.
