Question

Match List I with List II:

List I (Interaction)	List II (Species A, Species B)
A. Amensalism	I. +, −
B. Predation	II. −, −
C. Commensalism	III. +, 0
D. Competition	IV. −, 0

Choose the correct answer from the options given below:

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

Hint:

Interaction types are defined by how species benefit (+), are harmed (-), or are unaffected (0).

• Amensalism (A): A negative effect on one species and no effect on the other, which is represented by IV. -, 0.
• Predation (B): Involves one species benefiting (predator) and the other being harmed (prey), represented by I. +, -.
• Commensalism (C): One species benefits while the other is neither helped nor harmed, represented by III. +, 0.
