Correct option is B
The correct answer is: (B) Aphids
Explanation:
Aphids are the primary vectors (transmitters) of plant viruses. They feed on plant sap using their piercing-sucking mouthparts, and during this process, they can acquire and transmit viruses from infected to healthy plants.
Aphids are responsible for spreading a large number of economically important plant viruses, including Potyviruses, Luteoviruses, etc.
Information Booster:
Aphids can transmit viruses in different modes:
Non-persistent (stylet-borne)
Persistent circulative
Persistent propagative
They are highly mobile and reproduce rapidly, making virus control difficult in infested crops.
Example: Myzus persicae (Green peach aphid) is a common vector.
