Which of the following scenarios does NOT describe an event that leads to the conceptions of twins?
Select one:
A. two eggs are fertilized by two sperm cells, resulting in a fraternal twin.
B. High levels of FSH stimulate the maturation of three ovums.
C. Two eggs are fertilized by one sperm cell, resulting in a monozygotic twin.
