The correct option is C compensating
When two or more errors are committed in such a way that the net effect of these errors on the debits and credits of accounts is nil, such errors are called compensating errors. Such errors do not affect the tallying of the trial balance. For example, the debit side of XYZ's A/c was overcast by Rs. 1,000 resulting in the excess debit of Rs. 1,000, on the other hand, credit side of PQR's account, was overcast by Rs. 1,000 resulting in excess credit of Rs. 1,000, which is a case of two errors compensating each other's effect.
