4.4%.
6.1%.
2.4%.
9.8%.
Step 1: Understanding India's geographical extent.
India's landmass measures approximately 3.28 million square kilometers, representing about 2.4% of the Earth's total land area. The global land surface is estimated at 148.94 million square kilometers.
Step 2: Calculating India's proportion of global area.
The percentage of the world's land area occupied by India is determined using the formula: \[ \text{Percentage} = \left( \frac{\text{India's land area}}{\text{World's total land area}} \right) \times 100 \]
\[ \text{Percentage} = \left( \frac{3.28}{148.94} \right) \times 100 \approx 2.4\%. \]
Step 3: Evaluating alternative options.
Option (A): Incorrect. 4.4% is an overestimation of India's geographical share. Option (B): Incorrect. 6.1% is considerably larger than the actual percentage. Option (D): Incorrect. 9.8% is almost four times India's true proportion.
Step 4: Final conclusion.
India accounts for approximately 2.4% of the Earth's total geographical surface area. \[ \therefore \text{The correct answer is: 2.4\%.} \]
