The correct answer is: D.Exponential growth.

Explanation:

When a virus infects a host organism that lacks immunity, it can replicate rapidly without any significant resistance from the host’s immune system. This leads to exponential growth of the virus population, where the number of virus particles increases at a constant rate, doubling in size during each time period. Exponential growth occurs as long as there are enough resources (in this case, host cells) for the virus to replicate.

A.Logistic growth: This occurs when resources are limited, and growth slows down as the population reaches carrying capacity. This is not typi...
