Solution
The correct option is C Ectotherms
A poikilotherm is an animal whose internal temperature varies considerably. It is the opposite of a homeotherm, an animal which maintains thermal homeostasis. While the term in principle can apply to all organisms, it is generally only applied to animals, and mostly to vertebrates. The fluctuations are the consequence of variation in the ambient environmental temperature. Many terrestrial ectotherms are poikilothermic.So the correct answer is 'Ectotherms'.
