The graph depicts four possible patterns for the abundance of 3TC-resistant HIV within an infected human over time. If 3TC resistance is costly for HIV, then which plot (I—IV) best represents the response of a strain of 3TC-resistant HIV over time, if 3TC administration begins at the time indicated by the arrow?

 Following figure are shown figure of predator prey model 

Following some observation are given

A) The number of prey, N, increase at low predator densities, P, and decrease at high predator densities

B) Prey zero isoclines is depends on the ratio of the growth rate of prey to the capture efficiency of the predators

C) Number of predator needed for prey isoclines is depends on the ratio of the death rate of predators to the conversion efficiency of predators

D) Number of predator for prey isoclines depends on the ratio of the death rate of prey to the conversion efficiency of predators
