select one:
a.) Higher than normal FSH and LH levels due to fewer negative feedback messages being sent to the ovaries
b.) Lower than normal FSH and LH levels due to more neagtive feedback messages being sent the pituitary gland
c.) Higher than normal FSH and LH levels due to fewer negative feedback messages being sent to the pituitary gland
d.) Lower than normal FSH and LH levels due to more neagtive feedback messages being sent the ovaries

I would say B. This is why:
FSH and LH are the hormones that stimulate ovum development (FSH) and ovulation (LH). Another thing they do is secret estrogen and progesterone. These two work in a negative feedback loop to ensure that no more than one ovum matures during one cycle - or, in other words, high levels of both FSH and LH tell the brain to stop producing GnRH, which in turn leads to shutting down production of FSH and LH, etc. This is essentially a quick overview of a menstrual cycle.
So, the reason why it would produce LOWER FSH and LH is because birth control pills (artificial progesterone or artificial estrogen) tells the pituitary gland to stop producing GnRH! It is basically tricking the brain into thinking it has already matured one ovum, and does not need to produce the hormones to ensure the maturation of another.
I hope this helps!
