• B. Better health care

Answer 1

The correct option is C

Immigration

There are two main factors for the increase in human population: (a) Decrease in death rate mainly maternal mortality rate (MMR) and infant mortality rate (IMR) and (b) Increase in the span of life. Better health, fewer deaths, minimised food shortages, improved nutrition, large-scale immunisation and fewer infant deaths are the major reasons for the sharp rise in world human population in the recent past.
