The Ghanaian Government Wants an Accurate Measure of Fertility Rates

The Ghanaian government wants an accurate measure of fertility rates, so it employs a sociologist to measure:

A) how many children an average woman could possibly have subtracted by the number of children the average woman actually has
B) the key factors in the second demographic transition that are at play in Ghana
C) which stage in the demographic transition best describes Ghana and then apply fertility statistics from that stage
D) the number of live-born children the average Ghanaian woman has
