Final answer:
Viruses can move throughout the whole plant primarily through the phloem tissue and plasmodesmata. OPTION B IS ANSWER
Step-by-step explanation:
Viruses can move throughout the whole plant primarily through the phloem tissue. Phloem is one of the two types of vascular tissue in plants and is responsible for transporting sugars
Proteins, and other solutes throughout the plant. Phloem cells, specifically the sieve elements, act as conducting cells and allow for the movement of viruses along with other substances.
In addition to phloem, structural modifications called plasmodesmata also enable the movement of materials from cell to cell, thus aiding in the transport of viruses throughout the plant. Plasmodesmata are numerous channels that connect the cytoplasm of adjacent plant cells, allowing for the transfer of substances from cell to cell. OPTION B IS ANSWER
