Answer:
The best choice of the four listed is option a. There is less risk that the borrower will be unable to repay the loan.
Explanation:
In an annuity loan, the payment plan is scheduled in many time intervals, meaning that you will have a lot of time to pay the lender money, no matter how small the amount is. The person borrowing is made to pay money, during this time window, many small amounts of money. Since the borrower will be paying small amount of money from time of time until he or she is done repaying, the lender has an advantage in this situation as they will not be losing money.
