Answer:
Auto loan
Step-by-step explanation:
The auto loan is a credit to buy a vehicle in which the monthly payments are established in the beginning and they are the same until the loan is paid in full. Because of this, the answer is auto loan.
The other options, revolving line and credit card are not correct because these options don't have a set payment schedule as they payment you have to make depends on the amount you use from the total sum approved which can vary all the time according to your needs.
