What is the method of virus transmission in plants?

The method of virus transmission in plants primarily occurs through seeds and insects, making this the correct choice.

When a plant is infected with a virus, the infection can be passed on to the next generation of plants through seeds produced by the infected plant. This direct transmission ensures that the virus can persist and spread within the plant population. Additionally, insects such as aphids, beetles, and whiteflies serve as vectors that can carry viruses from one plant to another as they feed. Their feeding activities often result in the introduction of viral particles into healthy plants, facilitating the spread of infection.

Understanding these transmission methods is essential in the context of plant pathology and crop management, as controlling the vectors and managing seed transmission can be crucial strategies in preventing viral outbreaks in crops.
