Brief Explanations:

Endothermic organisms, also known as warm - blooded animals, generate heat internally to maintain a stable body temperature. Exothermic refers to heat - releasing chemical reactions in a non - biological context here. Homeostasis is the general process of maintaining a stable internal environment but not specific to body temperature maintenance only. Metabolism is the set of chemical reactions in an organism for life processes, not directly related to maintaining a constant body temperature as the term asked.

Answer:

B. ENDOTHERMIC
