Answer: (B)

(a) - (iii), (b) - (i), (c) - (ii), (d) - (iv)

• Exocoetus is the scientific name of the flying fish. They have fins that have been modified like wings. They can fly on the surface of the water bodies.
• Draco is a genus of agamid lizards. They are also known as flying dragons. The ribs and their connecting membrane may be extended to create a wing.

Echidna belongs to monotremes that lay eggs. Their optical system is an uncommon hybrid of both mammalian and reptilian characteristics. The cartilaginous layer beneath the scleral layer of the eyeball is similar to that of the reptiles. So, they are called as 'connecting link' between reptiles and mammals.

• Struthio is a genus of bird in the order Struthioniformes. Ostrich belongs to this genus and is the largest living species of bird which lays the largest eggs of any living bird.

Thus, the correct answer is option B.
