Answer:
A. PfEMP1
Explanation:
PfEMP1 stands for <em>Plasmodium falciparum</em> erythrocyte membrane protein-1. These antigens play a very important role in host immune invasion. Production of antibody against PfEMP1 antigens has been shown to contribute to natural immunity.
Malaria is associated with the parasites exhibiting an antigenically distinct <em>Plasmodium falciparum</em> erythrocyte membrane protein-1 subset thereby mediating binding to endothelial receptors.
