If A was supposed to be credited but no entry was passed, what correction should be made?

Correct answer: A will be credited

For an omitted entry you must record the effect that was originally intended. If A was to be credited but no entry was passed, the correction is to credit A (and debit the corresponding account). Option A is wrong because debiting A would give the opposite effect; option C is unrealistic (double debit) and option D is wrong because omissions must be corrected. Exam tip: identify the original intended debit–credit pair and pass the missing entry as it should have been, not its reverse.
