Why is birth and death registration considered necessary for planning in the National Population Policy?

Correct answer: Because it provides accurate population data

Direct answer: A is correct. Birth and death registration records vital events in a population: how many births and deaths occur, when they occur and where they occur. Planners can use these records to understand population change, estimate service needs and identify areas requiring stronger health support. For example, birth data helps estimate future demand for schools and immunisation, while death data can reveal health problems and the need for hospitals or maternal care. Without reliable registration, some people or events may be missed and plans may be based on incomplete evidence. B is wrong because registration does not directly determine train fares. C is wrong because administrative records cannot form mountains. D is wrong because registration has no power over rainfall. Memory cue: registration turns life events into useful evidence for planning.
