B
Animals that get heat from their surrounding.
C
Animals that eat a lot of ice.
D
Animals that live on the land.
Explanation: 

Detailed explanation-1: -Cold-blooded animals can be defined as animals that cannot regulate their internal body temperature with the change in the environment. They cannot survive in extreme temperature conditions. Examples of cold-blooded animals are reptiles, fish, etc.

Detailed explanation-2: -Since cold-blooded animals cannot generate their own heat, they must regulate their body temperature by moving to different environments. You probably have seen a lizard, turtle, or alligator lying around basking in the sun. It does this to raise its body temperature.

Detailed explanation-3: -The term “cold-blooded” implies that these animals are in a never-ending struggle to stay warm. That really isn’t correct. Many species do like it hot, with some monitor lizards basking at temperatures of 120–150 F.

Detailed explanation-4: -Cold-blooded animals do not maintain a constant body temperature. They get their heat from the outside environment, so their body temperature fluctuates, based on external temperatures.

Detailed explanation-5: -Cold-blooded creatures can’t generate their own heat, therefore they have to maintain their body temperature by moving about. Cold-blooded creatures become less active, even lethargic, as the temperature drops.
