Solution
The correct option is B B
In the bottleneck effect, there is a reduction in the size of a population due to environmental events or calamities. There is a reduction in the variation of the gene pool of a population. The smaller population with a correspondingly smaller genetic diversity. The genetic diversity will slowly increase with time as random mutations occur. In the graph. after the point B, there is a reduction in the size of the population. This is the point when the bottleneck event takes place. Thus, the correct answer is option B.
