Choice A rationale:

Antibiotics are not effective against viruses like herpes, so they cannot cure genital herpes.

Choice B rationale:

While antiviral drugs can help manage genital herpes, they do not completely eliminate the herpes virus from the body. The virus can become dormant and reactivate.

Choice C rationale:

This is the correct answer. Antiviral drugs like acyclovir or valacyclovir are commonly used to manage genital herpes by reducing the frequency and severity of outbreaks.

Choice D rationale:

Topical agents cannot provide a permanent cure for genital herpes, as the virus resides in nerve cells and cannot be entirely eradicated by topical treatments.
