Dont guess i beg you not to i have to get it !

which of the following is an organ in the respiratory system?

a. thyroid

b. hypothalamus

c. pancreas

d. larynx

I'm positive that it's the larynx since; the pancreas is an organ behind the stomach, the hypothalamus is a part of the brain, and the thyroid is a part of the neck. The larynx is commonly known as your voice box, helps you speak. That's a part of your respiratory system.

if u need the answers look it up on google youll find it trust im just saying this incase no one out : )
