Choose the correct answer from the options given below:

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

Hint:

The vector for Banana bunchy top virus is the banana aphid (Pentalonia nigronervosa).
Matching (D) with (III) immediately simplifies identifying the correct option.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Many destructive plant viruses are transmitted from infected to healthy host plants by specific insect vectors, which primarily belong to orders like Hemiptera and Thysanoptera.

Step 2: Detailed Explanation:
Let us analyze the specific insect vector relationships for each virus:
Rice dwarf virus is a plant reovirus transmitted in a persistent propagative manner by the green rice leafhopper, Nephotettix cincticeps (and other Nephotettix species).
Thus, (A) matches with (I).
Tomato spotted wilt virus is a tospovirus transmitted specifically by thrips, with Frankliniella schultzei (and Thrips tabaci) acting as major vectors.
Thus, (B) matches with (II).
Groundnut rosette virus is an aphid-borne virus transmitted specifically by the groundnut aphid, Aphis craccivora, in a circulative, non-propagative manner.
Thus, (C) matches with (IV).
Banana bunchy top virus is a single-stranded DNA virus transmitted in a persistent, non-circulative manner by the banana aphid, Pentalonia nigronervosa.
Thus, (D) matches with (III).
This matching sequence is: (A)-(I), (B)-(II), (C)-(IV), (D)-(III).

Step 3: Final Answer:
The correct match is (A) - (I), (B) - (II), (C) - (IV), (D) - (III).
