Accepted Answer

Seroprevalence refers to the number of individuals in a population who have antibodies to a specific disease. Therefore, the best choice is D, which states "number of people who have antibodies to a particular disease." A refers to the presence of antibodies in serum, which is correct but less specific. B and E refer to immunity and absence of disease, respectively, but do not specifically relate to antibodies. C refers to the overall prevalence of a disease, but does not specifically address the presence of antibodies.
