A
Explanation
Pair 1 is correctly matched: The period from 1901-1921 is referred to as a period of stagnant or stationary phase of growth of India’s population, since in this period the growth rate was very low, even recording a negative growth rate during 1911-1921. Both the birth rate and death rate were high keeping the rate of increase low.
Pair 2 is incorrectly matched: The decades 1921-1951 are referred to as the period of steady population growth. An overall improvement in health and sanitation throughout the country brought down the mortality rate.
Pair 3 is incorrectly matched:The decades 1951-1981 are referred to as the period of population explosion in India, which was caused by a rapid fall in the mortality rate but a high fertility rate of population in the country. The average annual growth rate was as high as 2.2 per cent.
