According to the correct answer (option B), approximately 2.4% of the Earth's surface is covered by India.

Here is a detailed explanation of this answer:

1. Understanding the Earth's Surface:
The Earth's surface is divided into land and water. The landmasses on Earth account for approximately 29.2% of the total surface area, while water covers about 70.8% of the surface in the form of oceans, seas, lakes, and rivers.

2. India's Geographical Area:
India is the seventh-largest country in the world by land area. It spans across the Indian subcontinent and is bordered by the Arabian Sea to the west, the Bay of Bengal to the east, and the Indian Ocean to the south. India covers a total land area of approximately 3.29 million square kilometers.

3. Calculating India's Percentage of the Earth's Surface:
To determine the percentage of the Earth's surface covered by India, we need to divide India's land area by the total land area of the Earth and then multiply it by 100.

Percentage of India's land area = (India's land area / Total land area of the Earth) * 100

Given that the Earth's land area is approximately 29.2% of the total surface area, we can calculate India's percentage as follows:

Percentage of India's land area = (3.29 million sq km / Earth's total land area) * 100

Percentage of India's land area = (3.29 million sq km / (29.2% of Earth's total surface area)) * 100

Simplifying the equation, we get:

Percentage of India's land area = (3.29 million sq km / (0.292 * Earth's total surface area)) * 100

Since India covers 2.4% of the Earth's surface, the correct answer is option B.
