Options
- A(A)-(III), (B)-(II), (C)-(I), (D)-(IV)
- B(A)-(II), (B)-(III), (C)-(I), (D)-(IV)
- C(A)-(II), (B)-(III), (C)-(IV), (D)-(I)
- D(A)-(III), (B)-(II), (C)-(IV), (D)-(I)
Correct answer
B. (A)-(II), (B)-(III), (C)-(I), (D)-(IV)
Step-by-step solution
The thorax of a cockroach consists of three segments: prothorax, mesothorax, and metathorax. (A) Tegmina (forewings) arise from the mesothorax. (B) Hindwings arise from the metathorax. (C) The pronotum is the large dorsal sclerite that covers the prothorax. (D) Each of the three thoracic segments bears one pair of walking legs, meaning they are present on all thoracic segments. Therefore, the correct matching is (A)-(II), (B)-(III), (C)-(I), (D)-(IV). Answer: (A)-(II), (B)-(III), (C)-(I), (D)-(IV)
