Solution

The correct option is A Genetic make up of particular sperm which fertilizes the egg
In the XY sex-determination system, the female-provided ovum contributes an X chromosome and the male-provided sperm contributes either an X chromosome or a Y chromosome, resulting in female (XX) or male (XY) offspring, respectively. Hence, Genetic make up of particular sperm plays a deciding role.

So, the correct answer is 'Genetic make up of particular sperm which fertilizes the egg'.
