The correct option is A) An endotherm can be active anytime of the year or day.

Explanation:

Endothermic organisms can be described as organisms which have the ability to maintain their internal temperature even when the conditions outside are not favourable. Such organisms are also known as warm blooded organisms. One benefit of maintaining temperature is that these organisms can be active at any time of the year. In contrast, those organisms which cannot maintain their internal environment have to hibernate during unfavourable conditions.
