Options
- A(A) - (I), (B) - (III), (C) - (II), (D) - (IV)
- B(A) - (II), (B) - (III), (C) - (I), (D) - (IV)

- D(A) - (III), (B) - (I), (C) - (IV), (D) - (II)
Correct answer
C. (A) - (II), (B) - (IV), (C) - (III), (D) - (I)
Step-by-step solution
Coelenterates exchange gases through simple diffusion over their entire body surface, which corresponds to the plasma membrane. Limulus, commonly known as the king crab, is an aquatic arthropod that respires using book gills. Birds are terrestrial vertebrates that use lungs for respiration. Salamanders, which are amphibians, often possess external gills for respiration, especially in their larval or neotenic stages. Thus, the correct matching is (A) - (II), (B) - (IV), (C) - (III), (D) - (I). Answer: (A) - (II), (B
