Vertical transmission refers to the transmission of a virus from a parent plant to its progeny (e.g. through seeds or vegetative propagation), while horizontal transmission refers to the spread of the virus from one plant to another (e.g. via insects, contaminated tools, or contact with infected plant tissue). The other statements either describe different aspects of transmission or are incorrect.
