Correct Answer: Option (D) — Neither 1 nor 2

Concept & Option Breakdown

Standard Reference Verified

Statement 1 is incorrect: The population density of India was 117 persons/sq km in 1951 and rose to 324 persons/sq km in 2001. This is an increase of 324/117 ≈ 2.77 times, which is less than three times.

Statement 2 is incorrect: The annual exponential growth rate was 1.25% in 1951 and 1.93% in 2001. This represents an increase of approximately 54%, not a doubling (100% increase).

Elimination Heuristic & Exam Approach

Population in 1951 was ~361 million, in 2001 was ~1028 million (increase factor = 2.85). Since area is constant, density also increased by < 3 times.
