Final answer:
A journal entry is needed for (Option A) bank service charges during bank reconciliation because these charges affect the company's cash balance and are not yet recorded in the company's books. Deposits in transit, bank errors, and outstanding checks typically do not require journal entries by the company since they're timing issues resolved by normal banking processes.
Step-by-step explanation:
A journal entry is required for certain adjustments made during a bank reconciliation process. One such adjustment is for bank service charges, which represent fees charged by the bank for account servicing and various banking transactions. Since these charges may not be reflected in the company's cash account records until the reconciliation is performed, the company needs to record a journal entry to acknowledge the expense and reduce its cash balance accordingly. Therefore, an adjustment for bank service charges necessitates a journal entry.
On the other hand, deposits in transit, bank errors to be corrected by the bank, and outstanding checks do not require journal entries from the company’s perspective, since they are usually timing differences and will be resolved without the company needing to alter its books.
