The correct option is B. deposits. Explanation of Why the Answer is Correct In the context of a commercial bank's balance sheet, liabilities are obligations that the bank owes to others. These can include various forms of debt or money that the bank must repay. Let's break down the options to understand why deposits are considered a liability:

1. Understanding Liabilities:
2. A liability is a financial obligation that a bank has to pay back. This can include loans taken by the bank, money owed to depositors, and other forms of debt.
3. In the case of a commercial bank, when customers deposit money into their accounts, the bank is obligated to return that money upon request. Therefore, these deposits are classified as liabilities on the bank's balance sheet.
4. Deposits as Liabilities:
5. When you deposit money in a bank, you are essentially lending that money to the bank. The bank uses these funds to make loans and investments, but it must keep a record of how much it owes to its depositors.
6. For example, if you deposit $1,000 in your savings account, the bank records this as a liability because it must return that $1,000 to you when you withdraw it.

Why the Other Options are Wrong or Weaker Now, let’s analyze the other options to understand why they do not qualify as liabilities:

• A. Advances:
• Advances refer to loans that the bank gives to its customers. These are considered assets for the bank because they represent money that the bank expects to receive back with interest. Therefore, advances are not liabilities; they are a source of income for the bank.
• C. Treasury Bills:
• Treasury bills (T-bills) are short-term government securities that banks can purchase. These are also considered assets because they represent an investment that the bank has made. The bank expects to earn interest on these securities, so they do not represent an obligation to pay anyone.
• D. Overdrafts:
• An overdraft occurs when a customer withdraws more money than is available in their account, leading to a negative balance. While the bank may charge interest on this amount, overdrafts are not liabilities of the bank; rather, they are a form of credit extended to the customer. The bank expects to recover this amount from the customer, making it an asset rather than a liability.

Summary of Key Points

• Deposits are liabilities for a bank because they represent money that the bank must return to its customers.
• Advances are assets, as they are loans made by the bank to customers.
• Treasury Bills are also assets, representing investments made by the bank.
• Overdrafts are a form of credit extended to customers and are considered assets, not liabilities.

Revision Summary

• Deposits are classified as liabilities because the bank must return this money to customers.
• Advances and Treasury Bills are assets, not liabilities.
