Solution
The correct option is B Camouflage Camouflage refers to adaptation wherein organisms blend themselves with certain surroundings to avoid predators. A walking stick insect camouflage itself to disguise and be protected from the predators. This method of blending with the surrounding is used as a protective device. The eggs of the frogs are camouflaged with the colour of the leaves. This provides protection against the other birds to feed on the eggs.
