60 POINTS!! PLEASE HELP!!When the level of blood testosterone has increased past its set point, a negative feedback signal will be sent to the hypothalamus.


Based on the diagram, what will be the result of this signal?

A) The hypothalamus will stop production of gonadotropin-releasing hormone. As a result, the production of follicle-stimulating hormone will increase and testosterone levels will decrease.

B)The hypothalamus will stop production of gonadotropin-releasing hormone. As a result, follicle-stimulating hormone will no longer be produced and testosterone levels will start to decrease.

C)The hypothalamus will stimulate production of gonadotropin-releasing hormone. As a result, the production of follicle-stimulating hormone will increase and testosterone levels will increase.

D)The hypothalamus will stimulate production of gonadotropin-releasing hormone. As a result, the production of follicle-stimulating hormone will be inhibited and testosterone levels will decrease.
