What would you expect to find in a country with zero population growth?

a) a high birthrate and a low death rate

b) a low birthrate and a high death rate

c) about equal birthrates and death rates

d) low birthrates and death rates

C because the other answers are not logical. A would mean that the population is growing in size. B would mean that a country's population is rapidly declining. D does not give enough information to identify which is higher or lower, nor does it say they are equal. If you have equal birth and death rates, the population will not change.
