Answer:
I'm pretty sure it is B, because of natural selection
It helps to give solid evidence of natural selection. The idea is that there are a number of finches in the Galapagos Islands. These birds vary slightly in appearance, in the function of their beaks and in size. Two species can eventually alter themselves because of the environmental conditions they live in. Some traits will be passed on or developed in one group and not in the other or vica versa. These finches are remarkable in that it did not take long for the changes to take place. It is probably one of the strongest reasons for believing in natural selection, because only those birds who could adapt to change could easily pass on these advantages to their offspring. The relatively short period of time to enact these changes is what makes the this example so attractive.
Some wisdom teeth is completely unharmful, as long as your mouth have enough space for it to grow healthy and you are sure that you can clean it properly, they make no problems.
However, if your mouth is too small, wisdoms teeth may grow in a tilted angle, this is big problem indeed. It may cause damage to other teeth since it doesn't grow upright. In addition, it may be a big problem to clean it properly so tooth decay may occur.
Therefore, it's better to visit the dentist and see if your wisdom teeth cause problem and whether you need to remove them or not.
