Correct Answer: Option D

D. more restraint is adopted

Explanation

Positive checks are those, according to Thomas Malthus, that increase the death rate. These include disease, war, disaster, and finally when other checks don’t reduce the population, famine. Malthus felt that the fear of famine or the development of famine was also a major impetus to reduce the birth rate.
