Correct Option: B. A credit balance on a savings account Detailed Explanation: Liquidity refers to how easily an asset can be converted into cash without significant loss of value. The more liquid an asset is, the quicker and easier it is to access cash from it. Let’s analyze each option to understand why a credit balance on a savings account is the most liquid asset among the choices provided.

1. Outstanding balance on the current account of a commercial bank (Option A):
2. A current account typically allows for easy access to funds, and the balance can be withdrawn at any time. However, while it is quite liquid, it is often used for day-to-day transactions and may not earn interest like a savings account.
3. Liquidity Level: High, but not as high as a savings account in terms of earning potential and ease of access for larger amounts.
4. A credit balance on a savings account (Option B):
5. A savings account holds funds that can be accessed relatively easily, often through ATMs or bank transfers. The key advantage is that it typically earns interest, making it a more attractive option for holding cash over time.
6. Liquidity Level: Very high. Funds can be accessed quickly, and the account earns interest, making it the most liquid option here.
7. A crossed postal order (Option C):
8. A crossed postal order is a form of payment that can be used to send money securely. However, it is not as liquid as cash or bank balances because it must be cashed at a post office or bank, which may involve additional steps and time.
9. Liquidity Level: Moderate. It can be converted to cash, but the process is less direct than accessing funds in a bank account.
10. An insurance policy (Option D):
11. An insurance policy is a contract that provides financial protection against certain risks. While it may have a cash value if it is a whole life policy, it is not liquid in the sense that it cannot be easily converted to cash without potentially significant delays and penalties.
12. Liquidity Level: Low. It is not designed for quick access to cash and often requires a lengthy process to cash out.

Why Other Options Are Weaker:

• Option A (Current account balance) is liquid but does not typically earn interest, making it less favorable compared to a savings account.
• Option C (Crossed postal order) requires additional steps to convert to cash, making it less liquid than a bank account.
• Option D (Insurance policy) is the least liquid, as it involves a lengthy process to access cash and is not intended for immediate cash needs.

Common Pitfalls:

• Students may confuse liquidity with the ability to earn interest. While both are important, liquidity specifically refers to how quickly and easily an asset can be converted to cash.
• It’s essential to consider not just the ease of access but also the potential for earning interest when evaluating financial assets.

Revision Summary:

• Liquidity is the ease of converting an asset to cash.
• A savings account is highly liquid and earns interest, making it preferable for holding cash.
• Current accounts are liquid but typically do not earn interest.
• Other options like postal orders and insurance policies are less liquid due to additional steps required to access cash.
