Explanation:

- India, being a vast country, has numerous international airports spread across its territory.

- These airports serve as key gateways for international travel and play a crucial role in tourism and trade.

- Option 1 (15): This number is too low for a country of India's size and international traffic needs.

- Option 2 (30): Close, but still underestimates the actual number of international airports in India.

- Option 3 (34): This is the correct option as India has 34 international airports.

- Option 4 (16): Also insufficient, not representing the extent of India's international connections.
