Answer:

(c) Decrease in infantile mortality is ur correct answer

Answer 2

The decrease in infantile mortality has

contributed most in the rapid rise of the human population in the present century.

* According to the World Health Organisation( WHO), the infant mortality rate has reduced from 65 deaths/1000 live births ( 1990) to 29 deaths/1000 live births( 2017).

* Infant mortality refers to the death of newborns or children under the age of 1 year.

* A greater investment or spending in the public health and sanitation has led to this huge decline in infant mortality rate.

* The introduction of modern medical facilities, proper immunization, antibiotics, etc. has contributed towards the fall in the infant mortality rate.

This has in turn given rise to an increase in the population of the country.
