While preparing the bank reconciliation, you notice that a check, written by the company for $720, has been outstanding for 5 months. What is the best action for you to take?

a. Void the check. If it has not been cashed in 5 months, it will never be cashed.

b. Wait 3 more months to give the bank more time to clear the check.

c. Issue a replacement check because you assume the original check has been lost.

d. Investigate to determine why the check has not cleared.
