Solution

The correct option is C Assertion is correct but Reason is incorrect
Fertilizin is a chemical substance produced from the egg. It combines with the sperm antifertilizin of the same species. The main function of the fertilizin antifertilizin complex is to minimize the number of spermatozoa around the egg, so that the chances of polyspermy i.e. two or more spermatozoa fusing with the egg at the same time can be diminished. So, the correct option is C.
