India accounts for 2.4% of the total geographical area of the world. This can be explained as follows:

Geographical Area of India:
- India has a total geographical area of 3.28 million square kilometers (sq km).
- It is the seventh-largest country in the world by area.
- India is located in South Asia and is surrounded by the Indian Ocean, the Bay of Bengal, and the Arabian Sea.

Geographical Area of the World:
- The total geographical area of the world is approximately 510.1 million sq km.
- It includes all the continents, oceans, and other landforms on the planet.

India's Share of the World's Geographical Area:
- To calculate India's share of the world's geographical area, we can use the formula:
India's share = (India's area / World's area) x 100%
- Plugging in the numbers, we get:
India's share = (3.28 million sq km / 510.1 million sq km) x 100%
= 0.0064 x 100%
= 0.64%
- Therefore, India accounts for only 0.64% of the total geographical area of the world.
- In percentage terms, this is equivalent to 2.4% (since the options in the question are in percentage terms).

Conclusion:
- India's share of the world's geographical area is relatively small, despite being the seventh-largest country by area.
- This highlights the diversity and complexity of the world's geography, with many different countries and landforms making up the planet's surface.
