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.

Tyrosine is listed as a non-essential amino acid because it can be synthesised from the essential amino acid phenylalanine.
<u>Explanation:</u>
Amino acids are classified as essential and non essential according to whether they can be synthesized in the body itself or should be supplied by the diet. Essential amino acids cannot be synthesized in the body of the organism and thus can be obtained only from the diet. In the case of human beings, valine, phenylalanine, methionine etc are examples of essential amino acids.
Non essential amino acids can be synthesized within the body of the organism. Thus they need not be supplied by the diet. Alanine, aspartic acid etc are some of the non essential amino acids in human beings. It is given here that animals cannot synthesize tyrosine from shikimate-3p due to the lack of EPSP synthase.
But the amino acid tyrosine can be synthesized from the amino acid phenylalanine which is an essential amino acid. Thus tyrosine will be a non-essential amino acid.
