The female gonads : a. usually release only one ovum per month from the ovarian follicle
b. release a fertilized egg monthly into the fallopian tubes
c. all of the above
d. have continuous gametogenesis

a. usually release only one ovum per month from the ovarian follicle

Explanation:

The "female gonads" is also known as the "ovaries." These are located on both ends of the uterus (the left ovary and the right ovary). It is during the "ovulatory phase" that one of the ovaries releases one ovum or egg cell from the ovarian follicle/ovary. This egg travels through the Fallopian tube where it meets the sperm cell (if an intercourse occurred) in order for it to be fertilized.

So, this means that the egg may not be fertilized monthly into the fallopian tubes if no intercourse occurred. This makes choice b incorrect.

The gametogenesis in females in known as "oogenesis" and it is not continuous like the "spermatogenesis." It has a limit or an end. So, this makes choice d incorrect.

c would be the answer
