Answer 1

The Correct Option is D

Statement I is incorrect because in commensalism, only one partner is benefitted while the other is neither benefitted nor harmed.
Statement II is correct as in amensalism, no partner is benefitted; one is harmed while the other is unaffected.
Statement III is correct because in parasitism, one partner (the parasite) benefits at the expense of the other (the host).

Final Answer:
I, IV
