Show answer & explanation

Correct answer: C

To match the biotic interactions with their effects, analyze each relationship:

Amensalism (A) occurs when one species is harmed while the other remains unaffected, matching effect (III).

Mutualism (B) is a relationship where both species benefit, corresponding to effect (IV).

Commensalism (C) involves one species benefiting while the other is unaffected, matching effect (I).

Parasitism (D) describes a scenario where one species benefits at the expense of the other, corresponding to effect (II).

Therefore, the correct matching is A-III, B-IV, C-I, and D-II.
