The correct answer is: It can take three months for antibodies to the virus to show up in an infected person’s blood.

This is because the body typically takes time to produce antibodies after an HIV infection, and testing too soon may result in a false negative. After exposure, it is recommended to have follow-up tests at intervals (such as three months) to ensure accurate results.
