  4. D.pre-reproductive individuals are less than the reproductive individuals.

Correct Answer

(C) pre-reproductive individuals are more than the reproductive individuals.

Solution & Explanation

Answer: (C) pre-reproductive individuals are more than the reproductive individuals. Solution: A growing population has an expanding (broad-based, triangular) age pyramid in which the pre-reproductive age group is the largest, exceeding the reproductive group, which in turn exceeds the post-reproductive group — reflecting high natality and future growth. NCERT: Ch 11, p.191, lines 42-45 — "The shape of the pyramids reflects the growth status of the population - (a) whether it is growing, (b) stable or (c) declining."
