Possible response:

Account with Credit Balance

Definition: A credit balance is the amount by which credits exceed debits in an account.

Analysis: Since the account in question has a credit balance, it means that the total credits recorded in that account exceed the total debits recorded in that account. Therefore, the account represents a liability or an income, depending on its nature.

Options: Based on the given options, we can eliminate a and c as possibilities, because Plant and Equipment A/c and Purchase A/c are asset accounts, which normally have debit balances. Therefore, the answer must be either b or d.

Solution: Sundry Creditors A/c is a liability account that records the amounts owed by the entity to its suppliers for the purchases made on credit. When the entity receives goods or services on credit, it records a credit entry in the Sundry Creditors A/c, which increases the balance of the account, and a debit entry in the Purchase A/c, which increases the total cost of goods sold or expenses. When the entity pays its creditors, it records a debit entry in the Sundry Creditors A/c, which decreases the balance of the account, and a credit entry in the Bank A/c or Cash A/c, which decreases the total cash or bank balance. Therefore, it makes sense that the Sundry Creditors A/c has a credit balance, which represents the amount of money the entity owes to its suppliers.

Conclusion: The correct answer is b. Sundry Creditors A/c.
