Answer:
The correct answer is option C. "pleiotropy".
Explanation:
Pleiotropy is a characteristic that defines a gene that is responsible for the development of multiple traits, which often seem to be unrelated. Sickle-cell disease is an example of a disease caused by the mutation of a pleiotropic gene, resulting in the person developing red levels, blood clots, and strokes. Other example is the disease phenylketonuria, at which the affected person suffers from a mental disorder and reduced hair and skin pigmentation by a single mutation in a single gene on chromosome 12.

Answer:
I wasn't quite sure what virus you were referring to in your question, but here's a general answer: Viruses use their host cells' machinery to replicate themselves.
If they are a specific type of virus known as a retrovirus, they have the ability to use the host cells' enzymes to change the RNA contained within the virus into DNA (via some type of replication I suppose).
In other cases, if they contain DNA instead of RNA (that is, the virus), they can use the host cell's machinery to create RNA via enzymes involved in transcription and/or they can incorporate that DNA into the host cell's DNA. This is part of a type of viral replication cycle known as the lysogenic cycle.
In another type of viral replication cycle known as the lytic cycle, the virus simply has itself and its genome duplicated until the host cell bursts, releasing the viral material. Here, again, the virus uses the host cell's machinery to replicate itself.
