The answer is option A.
The gonads of the male and
female body are regulated by Folicle-stimulating hormone (FSH) and
Luteinizing (LH) from the pituitary glandule. In males, FSH stimulates
production
of sperm cells while in females it stimulates the
growth of the ovum. And LH, in males, stimulates the Leydig cells in
order to produce testosterone, and in females, stimulates
hormones preparing the body for pregnancy, as well as playing an important role in ovulation.
