Correct Answer: Current account balance

Solution : The correct answer is (d) Current account balance

The capital account consists of various types of capital flows and transactions between a country and the rest of the world. It records the changes in a country's ownership of foreign assets and liabilities.

On the other hand, the current account balance is not a component of the capital account. The current account records the flow of goods, services, income, and transfers between a country and the rest of the world. It includes trade balances, income from investments, and unilateral transfers. It is separate from the capital account, which focuses on financial flows and changes in ownership.
