Match List-I (A. Both species are harmed, B. One species is harmed and the other is benefited, C. Both species are benefited, D. One is benefited while the other has no effect) with List-II (I. Predation, II. Mutualism, III. Competition, IV. Commensalism).
- A.A-III, B-IV, C-II, D-I
- B.A-I, B-II, C-III, D-IV
- C.A-II, B-I, C-IV, D-III
- D.A-III, B-I, C-II, D-IV✓
Correct Answer
(D) A-III, B-I, C-II, D-IV
Solution & Explanation
Competition: both species harmed (− / −) → A-III. Predation: one harmed, one benefited (+ / −) → B-I. Mutualism: both benefited (+ / +) → C-II. Commensalism: one benefited, other unaffected (+ / 0) → D-IV. So A-III, B-I, C-II, D-IV.
