Options

  1. A(A)-(III), (B)-(I), (C)-(II), (D)-(IV)
  2. B(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
  3. C(A)-(I), (B)-(III), (C)-(IV), (D)-(II)
  4. D(A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Correct answer

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

Step-by-step solution

(A) An orchid growing on a mango branch benefits by getting physical support and better access to light, while the mango tree is unaffected. This represents Commensalism (+, 0). (B) The relationship between the fig tree and the pollinator species of wasp is Mutualism (+, +), as the wasp pollinates the fig inflorescence and in return gets a site for oviposition and food for its larvae. (C) Copepods living on the body surface of marine fish derive nutrition from the host, which is harmed. This is an example of Ectopa
