Answer: The bank could sell the car.
Explanation:
A lien refers to a claim against an asset which is used as a collateral in order to satisfy a debt.
Since we are informed that Adam borrowed money to buy a new car and that the bank has a lien on the car, in a situation whereby Adam doesn't make his payments on time, the bank can end up selling his car and use the fund to settle the debt that he owes.
