The correct answer would be a. antiretroviral medications.

Human immunodeficiency virus (HIV) is a type of retrovirus that is, it has RNA as its genetic material.

HIV/AIDS presently does not have any cure or vaccine. It is treated with the help of antiretroviral drugs or medications.

These are the group of drugs which suppress the replication of HIV in our body. It is accomplished by inhibiting the viral replication process at different steps.

They are different categories of antiretroviral drugs:

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
