• A. I, III and IV
• B. II, III and IV
• C. I, II and III
• D. I, II and IV

Answer 1

The correct option is C I, II and III

In a region the population is always growing if the number of births is always higher than death. Thus, high birth rate and low death rate can add too many individuals in the existing population.
Better health care facilities and lifestyle can decrease the number of deaths and can have better life expectancy. All this coupled with high birth rate can cause the population to increase very rapidly.
