Answer 1

The correct option is C I- D, II- C, III- B, IV- A

Red-eyed tree frogs spend most of their time in trees and have sticky pads on their toes to help them move and jump about. The bright orange beak of Toucan is about 19 cm long one-third of the bird's total length. Composed of the protein keratin, the structure of beak incorporates many air pockets allowing for a very low mass.

Big cats (lions and tigers) have sensitive hearing, sharp eyesight and thick skin. The big cats of the jungle have thick skin for day and night protection. The polar bear has a very good sense of smell and can sniff dead animals from far away. A bear's sense of smell is around 100 times greater than a human's. Polar bears can track down an odour from 20 miles (32 km) away.

So, the correct answer is option C.
