Answer:
First Big Bank can file a lawsuit.
Step-by-step explanation:
Debbie took the loan when he has the job and agreed to refund the loan or borrowed money. Unfortunate circumstances lead to the loss of his job resulting in the stoppage of loan repayment. Since Debbie did not make any crime so it will not come under criminal law but the bank can file a lawsuit against Debbie and he will be liable to pay a fine and penalties.
