10) is most accurately describes a latent infection caused by a
virus.
The virus replicates in the host and the host cell is usually killed
by the release of the progeny viruses.
The virus genome has into the host cell, and possibly transformed
the cells into tumor cells.
The viral genome is inside the cell, but the genome is not
replicating or the virus is not doing harm to the cell.
The virus replicates in the host cell, and slowly releases virus
progeny with very few of the infected cells dying.
11) is suitable for cultivation of plant viruses.
Embryonated chicken Egg Tissue culture
