Which factor of obesity does activities such as eating and exercising fall under?
a. fat factor
b. genetic factor
c. behavioral factor
d. environmental factor

C - Behavioral factor.

Eating and exercising are of course two factors that we have control over. It is our conscious choice whether we're going to go to the gym and not eat at Mcdonalds today or if we're going to do that. With that being said, not going to Mcdonalds and going to the gym are two obviously goood behavioral choices that positively impact the chances of becoming obese. 

It is evolution, because we all have some of the same traits like eye color or shape or ears.
