- B.Mutualism
- C.Commensalism
- D.Amensalism✓
Correct Answer
(D) Amensalism
Solution & Explanation
Answer: (D) Amensalism. Solution: Antibiotic production exploits amensalism — a (−,0) interaction where one organism (e.g. the mould Penicillium) harms another (bacteria) by secreting an inhibitory chemical while itself remaining unaffected. This is the principle behind antibiotic action in medical science. NCERT: Ch 11, p.197, lines 8-10 — "In amensalism on the other hand one species is harmed whereas the other is unaffected."
