Solution

The correct option is C There is no variation.
As the sperm reaches ovum to fertilize it, the ovum gets activated and completes its second meiotic division. After fertilization, a diploid zygote is formed. Fertilization also helps in determining the sex of the offspring. On the one hand, it leads to inherent qualities of a parent and on the other hand, it is the means for variations among the populations.
So, the correct option is 'There is no variation'.
