Correct answer: (c) Population of 15-59 years is relatively high
Explanation
- A
Population of 0-14 years is relatively high
(a) 0–14 relatively high. A large child share raises the young-age dependency ratio; that would not explain a decline.
- B
Population of 60 years and above is relatively high
(b) 60+ relatively high. That raises old-age dependency, the opposite of a falling total ratio.
- C
Population of 15-59 years is relatively high
(c) 15–59 relatively high. A fatter working-age share (demographic dividend) lowers dependents per worker. (c) Official key.
- D
Population of 0-14 years and 60 years and above together are relatively high
(d) 0–14 and 60+ together relatively high. That is a high-dependency shape, not a declining ratio.
Summary. Official key is (c). India’s dependency ratio fell because the 15–59 working-age population became relatively large. High child or old-age shares would push the ratio up.
