Which option is the most suitable data set for studying population growth?

Answer and explanation

Correct answer: प्रारंभिक जनसंख्या, अंतिम जनसंख्या, जन्म, मृत्यु, प्रवास और समय अवधि

The direct answer is A. Studying population growth requires data that show how the number of people changes during a stated period. Initial population gives the starting total and final population gives the ending total. Births and deaths help explain natural increase or decrease. Migration records show the effect of people entering or leaving the area. The time period is essential because a change over one year has a different meaning from the same change over ten years. Together, these data allow a researcher to calculate absolute change, percentage change and the contribution of different processes. Option A is correct because it contains the main information needed to measure and interpret population growth. Option B describes physical relief features, not demographic change. Option C may be useful for agriculture or environmental study, but it does not measure population change. Option D may describe cultural composition, but a list of festivals and languages alone cannot show growth. Memory cue: to study growth, record “starting number, ending number, causes, and time.”
