Answer 1

ANSWER:-

Option (D) is correct because a polar bear does not hibernate due to colder surroundings around it. It is a warm-blooded animal which can maintain its body temperature even when the temperature is cold. The presence of a thick layer of fur and fat helps polar bear survive the harsh cold climate.

The P cell here represents an organism which hibernates due to cold and is cold-blooded, Q represents one which hibernates due to cold but is warm-blooded and R represents cold-blooded which does not hibernate due to cold. All these three options do not describe a polar bear.
