a. usually release only one ovum per month from the ovarian follicle
Explanation:
The "female gonads" is also known as the<em> "ovaries." </em>These are located on both ends of the<u> uterus</u><em> (the left ovary and the right ovary).</em> It is during the <em>"ovulatory phase"</em> that one of the ovaries releases<u> one ovum</u> or egg cell from the <em>ovarian follicle/ovary. </em>This egg travels through the<em> Fallopian tube</em> where it meets the<em> sperm cell </em>(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. <em>This makes choice b incorrect.</em>
The gametogenesis in females in known as "oogenesis" and it is not continuous like the "spermatogenesis." <u>It has a limit or an end</u>. So, <em>this makes choice d incorrect.</em>
