Answer:
Option D. three months after possible exposure.
Step-by-step explanation:
The concept behind HIV is the infection and the incubation period. The HIV virus infects a person and takes time before the results of the multiplication are seen. This is generally known as the incubation period. At 12 weeks, or at about 3 months, the body, after infection, will have developed specific antibodies for HIV virus. It is therefore important that the HIV virus be tested after such a period.
Testing in the shortest period can yield fake negative results as the virus has not fully developed.
