Options

A. cause rapid increases in growth rate
B. result in decline in growth rate
C. not cause significant change in growth rate
D. result in an explosive population /exp

Answer

C

Explanation

IMR (Infant Mortility Rat) and MMR (Meternal Mortility Rate) both are resonsible for affecting the grwoth rate inversely. It means decline in as well MMR will result in high population growth and vice-versa.
Here, If IMR has been increased than it will result in decline in growth rate. While, decreases MMR will cause rapid increases in growth rate.
Therefore, in the above situation, if IMR has been increases and MMR has been decreases in a population, it will not cause any significant change in growth rate.
