Complete Answer:
The cold blooded animals are the animals which cannot sustain extreme temperature as they do not have the capacity to regulate their body temperature. The body temperature is not fixed and it varies with respect to environmental temperature. They obtain energy from the surroundings and their rate of metabolism changes with the change in environment. Animals like amphibians, reptiles and fishes are cold blooded animals.

Now let us consider the given options.
A. Snakes and birds- Snake is a reptile and is cold blooded but birds are warm blooded.
B. Bats and rats- They are mammals and mammals have a characteristic feature of being warm blooded.

D. Birds and monkeys- Birds and monkeys both are warm blooded.

The correct answer is (C). Frog and snake are cold blooded animals.
