What was the main focus of the medium term objective of the National Population Policy?

Correct answer: Achieving replacement level fertility

The direct answer is B: the medium-term objective was to achieve replacement-level fertility. Replacement-level fertility is the level at which, over time, a population can replace itself from one generation to the next, when other conditions are considered. In policy planning, reaching this level is an intermediate step toward stabilising population size; it is not the same as suddenly stopping births or forcing every family to have an identical size. B is correct because it names the stated medium-term population objective. A is wrong because increasing the birth rate moves away from population stabilisation. C is wrong because city expansion is not the defining fertility objective. D is wrong because child-health programmes support welfare and are not to be removed. Memory cue: medium term means replacement fertility before long-term stabilisation.
