Answer: A. Omission

Explanation:
The answer is A because the error committed in failing to record an item entirely is referred to as an error of omission. This type of error happens when a transaction is completely left out from the accounting records, meaning that neither the debit nor the credit entry was made for it.

Run down:
The selected answer is A because an omission error means no part of the transaction was entered into the accounting records, which matches the situation where the wages were not recorded at all.
