If a person lacks the D antigen, what is their Rh status?

Explanation:
Rh status is determined by the presence or absence of the D antigen on red blood cells. If the D antigen is present, the person is Rh positive; if it is absent, the person is Rh negative. Since this scenario describes lacking the D antigen, the correct result is Rh negative. The other options don’t fit because Rh positive requires the D antigen, “not determinable” would imply the test couldn’t determine the status, and “both” is not biologically possible.
