Answer 1

Answer: (C)

Fossorial

Fossorial adaptation is seen in those animals which live underground and dig ground for their food. These animals are diggers and burrowers. In these animals, forelimbs are modified into broad, strong and stout limbs with long clawed digits as forelimbs are used to loosen the earth. Girdle bones are also modified to provide strength during digging. Examples of fossorial animals include moles, mole rat, hedgehogs, etc. Arboreal animals live on trees. Cursorial animals are runner. They are adapted to run fast. Volant animals are those which are adapted in such way that they are able to fly in air for long time.

Thus, the correct answer is option C.
