Which option correctly identifies population growth?

Answer and explanation

Correct answer: Population becoming 110 lakh from 100 lakh in a decade

The correct answer is A: the population has grown from 100 lakh to 110 lakh in one decade. Population growth means a change in the number of people over a stated period, usually because of births, deaths and migration. Here, the later population is greater than the earlier population: 110 lakh is 10 lakh more than 100 lakh. Option A therefore shows a real increase in population. Option B gives the length of a river, which is a physical measurement, not a population change. Option C gives the height of a mountain, another physical measurement unrelated to the number of people. Option D gives the area of a district; area is used with population to calculate density, but area alone is not population growth. Memory cue: growth means the later number is greater than the earlier number.
