Step 1: Read the clues in the question:
The account is held in India. It holds Indian income of an NRI, such as rent, dividends or pension. The interest on it is taxable in India.
Step 2: Recall the types of NRI accounts:
NRO means Non-Resident Ordinary Rupee Account. It is a rupee account used to manage income earned in India. Interest earned is taxable.
NRE means Non-Resident External Account. It holds foreign earnings sent to India, and its interest is tax free.
FCNR means Foreign Currency Non-Resident Account. It is a term deposit kept in a foreign currency.
Step 3: Match the clues:
Income earned in India plus taxable interest points to the NRO account. This is option (1).
Step 4: Why the other options are wrong:
(2) NRE holds money brought from abroad, and its interest is not taxed.
(3) FCNR is kept in foreign currency as a fixed deposit.
(4) A plain current account is a business account with no interest and does not suit this description.
Final Answer:
The account is the Non-Resident Ordinary Rupee Account (NRO), option (1).
