Options
- A(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
- B(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
- C(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
- D(A)-(III), (B)-(IV), (C)-(II), (D)-(I)
Correct answer
C. (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
Step-by-step solution
Pneumatic bones are long, hollow bones found in birds (Class Aves) to assist in flight. Corvus (crow) is a member of Aves, so (A) matches with (III). An air bladder is present in bony fishes (Class Osteichthyes) and regulates buoyancy. Pterophyllum (angelfish) belongs to Osteichthyes, so (B) matches with (IV). Placoid scales are characteristic of cartilaginous fishes (Class Chondrichthyes). Pristis (saw fish) belongs to Chondrichthyes, so (C) matches with (I). Crocodilus (crocodile) is a reptile (poikilotherm) but
