Dear student 
Ectotherm, any so-called cold-blooded animal—that is, any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface.
Poikilothermic 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.
Homeothermic, homoiothermic. warm-blooded - having warm blood (in animals whose body temperature is internally regulated)
Endothermic  dependent on or capable of the internal generation of heat.
 
A is correct one.
