Final Answer : C, Explanation :  Monozygotic twins, also known as identical twins, occur when a single fertilized egg (zygote) splits into two or more embryos. This happens when the zygote divides into two separate cells and each cell goes on to develop into a separate embryo. Therefore, the correct choice is C, where one egg is fertilized by one sperm and then splits.
