Following is a bank reconciliation for Zocar Enterprises for June $30,$ Year $1$:

Cash Account Bank Statement

Balance as of $6/30/$Year $1$ $ $1,918$ $ $3,000$

Deposit in transit $600$

Outstanding checks $(1,507)$

Note collected by bank $2,000$

Bank service charge $(25)$

NSF check $(1,800)$

Adjusted cash balance as of $6/30/$Year $1$ $ $2,093$ $ $2,093$

When reviewing the bank reconciliation, Zocar$$s auditor was unable to locate any reference to the NSF check on the bank statement. Furthermore, the clerk who reconciles the bank account and records the adjusting entries could not find the actual NSF check that should have been included in the bank statement. Finally, there was no specific reference in the accounts receivable supporting records identifying a party who had written a bad check.

Required:

a$.$ Prepare the adjustment that the clerk would have made to record the NSF check.

c$.$ Assume the clerk had stolen $$1,800$ cash, and recorded an entry for a nonexistent NSF check to reduce the cash balance so that it would match the bank balance. Select the internal control practice that would have most likely prevented this fraud.
