Agreement of trial balance is affected by:
Explanation
Option (A) is correct because one-sided errors affect only one aspect of a transaction (either debit or credit), causing an imbalance between the debit and credit columns of the trial balance. As stated in the context, 'difference in trial balance has arisen due to one sided error' and such errors 'cause a difference in trial balance and thus result in opening of the suspense account.' Two-sided errors, on the other hand, affect both debit and credit sides equally, so the trial balance will still tally despite the error. Therefore, only one-sided errors affect the agreement of the trial balance.
Solution Steps
Step 1: Understand that trial balance agreement means total debits equal total credits.
Step 2: One-sided errors affect only one side (debit OR credit), creating an imbalance.
Step 3: Two-sided errors affect both sides equally, so the trial balance still agrees.
Step 4: Conclude that only one-sided errors affect the agreement of trial balance.
