Aphids use specialized organs to pierce a plant and suck out the sap from the underside of leaves. during feeding, they can infect plants with viruses. which pathway would viruses most likely follow on first entering the plant?

A. Roots    B. Stem    C. Xylem    D. Phloem

The pathway that the viruses would most likely follow on first entering the plant is D. PHLOEM.

The phloem, whose purpose is to transport food from the leaves to the plant, is used as the pathway to spread the virus throughout the plant. The manifestation of aphid transmitted virus is the yellowing, mottling, or curling of leaves and the stunted growth of the plant. 

What is the example? i’ll be happy to answer if you can tell me : )
