antiviral drugs are often difficult to develop, largely because ______.
a viruses are obligate intracellular parasites so the drugs must enter the host cell and often cause toxic side effects in order to destroy the virus
b viruses are more pathogenic than bacterial cells
c viruses are more abundant in the body than bacterial cells
d viruses are much smaller than bacterial cells

Viruses are obligate intracellular parasites. Antiviral drugs need to enter host - cells to target the virus, which often leads to toxic side - effects on the host cells, making drug development difficult. Other options do not directly relate to the difficulty of drug development.

Answer:

A. viruses are obligate intracellular parasites so the drugs must enter the host cell and often cause toxic side effects in order to destroy the virus
