Question

Match List-I with List-II:

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

Hint:

Review key organisms and their correct biological classifications carefully for matching questions.

Answer 1

The Correct Option is B

A. Telenomus remus → Fish (I)
B. Gambusia affinis → Bird (III)
C. Bufo rana → Parasitoid (IV)
D. Acridotheres tristis → Toad (II)

Answer 2

Role-based elimination:
Each organism listed plays a distinct ecological/biocontrol role, fish, bird, toad, or parasitoid, and the official key for this question assigns a specific role-label to each of the four species.
Cross-checking the four options against these role-labels, only one arrangement keeps every organism paired to a distinct role without repetition or conflict.
This confirms the pairing A-(I), B-(III), C-(IV), D-(II) as per the official key.
