Would a Plant That Is Exposed First to a Virus

Would a plant that is exposed first to a virus and then to an herbivore be expected to have more than, less than, or the same amount of damage from herbivory as a plant exposed to just the herbivore and why?

A) more, because the threats are sufficiently different that the plant cannot coordinate an optimal defense against each threat at the same time
B) less, because the systematic required resistance triggered by the virus means the herbivores will encounter plants with heightened general defenses
C) the same, due to a trade-off between viral and herbivore defenses
D) the same, because viral defense and herbivore defense are nonoverlapping
