Answer:
The activity of cyclic AMP phosphodiesterase is prevented by caffeine. The caffeine prevents further dissociation of cAMP, which eventually increases the response within the body. The activity of neurotransmitters, that is, of noradrenaline or epinephrine, gets increased due to enhancement in response.  
This further enhances the activity of the heart, the rate of muscle contractions, blood pressure that further helps in delivering more oxygen to the brain, and other parts of the body. Thus, the inhibition of the enzyme cyclic AMP phosphodiesterase helps the athletes to prevent the wall.

We can also cross out A for the answers because the gallbladder is the organ that creates bile and that once again isn’t the picture of that organ.
That leaves C and B.
The stomach produces pepsin and makes hydrochloric acid, this isn’t a picture of the stomach, so that leaves you with C.
The answer to your question is C, since this is a picture of the pancreas, and the pancreas’ job is to produce enzymes that breaks down carbohydrates.
