Answer:
d.The post-closing trial balance is the only one to include only real accounts.
Explanation:
Post closing trial balance is prepared after providing for all the adjustments pending in the first raw trial balance.
Thus, it only represents the real accounts, as only real accounts have the balance to be carried forward, all the expenses and incomes are not real accounts and are thus, closed, and no carrying balance.
Whereas, all other trial balances will have the other accounts outstanding as well.
Thus, only statement D is correct in disclosing the difference between various trial balances.
