If a person gets tested for HIV and the results are negative, why might that person wait a few weeks and get tested again?

After HIV infection, the body needs time to produce enough antibodies for an antibody test to detect them. This delay is called the window period, so an early negative test may not rule out infection; retesting after several weeks can detect antibodies that have since developed. Therefore, the correct choice is D, HIV antibodies take several weeks to develop enough to be detected.
