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.

The point at which the toxin would interrupt normal cell signalling in the pathway is the signal amplification.
This is because of the G-protein uncoupling and inhibition of signal amplification by pertusis toxin. Pertusis toxin released by the bacteria Bordetella pertusis and prevents signal that is amplifying from the protein. The G-protein coordinates the interaction between membrane bound receptor proteins and the effector proteins involved in the intracellular signalling. The toxin promotes the uncoupling of this heterotrimetric protein and also inhibits the amplification thus preventing the interaction of the receptor proteins and the second messengers.
The biome that usually have this type of vegetation are tundras or polar grasslands.
