Which hormone signals ovulation?
fsh
lh
inhibin
estrogen

The correct answer is B. LH

Explanation:

The ovulation refers to a biological process in which eggs (reproductive cells) in females are released usually by ovaries or similar structures. This process is very important in reproduction because the ovulation means the fertilization can take place. Additionally, ovulation is mainly marked by the LH or Luteinizing hormone, because during ovulation there is a sharp spike in the levels of this hormone also there are other physiological signs such as a slight increase in basal temperature. In the case of the FSH or Follicle-stimulating hormone, this also plays an important role in the reproductive system including before ovulation because it stimulates the follicle, but it is the LH the hormone that marks the ovulation  as this rises only during ovulation.
