Question

Given below are two statements:
Statement (I): Bean yellow mosaic virus is transmitted by Aphis glycines.
Statement (II): Chilli mosaic virus is transmitted by Aphis craccivora.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Confirm virus-vector relationships carefully; they often differ by crop and aphid species.

Answer 1

The Correct Option is C

Bean yellow mosaic virus is indeed transmitted by Aphis glycines.
Chilli mosaic virus is not typically transmitted by Aphis craccivora.

Answer 2

Aphid-borne viruses are often strongly associated with a particular vector species; Bean yellow mosaic virus is well documented as being spread by Aphis glycines among other aphids, so the first statement stands. Chilli mosaic, however, is more commonly linked with whitefly-transmitted or other aphid species rather than specifically with Aphis craccivora, so pairing it with Aphis craccivora as stated is not accurate. Statement (I) is correct but Statement (II) is incorrect.
