sveticcg [70]

Answer:

So adaptive immune system is not able to recognize the trypanosome by its glycoprotein because the old surface glycoprotein against which the memory cells were produced previous time is now changed.

Therefore the immune system will not recognize the new generation of trypanosome with different variants of cell surface glycoprotein. Therefore the right answer is D.
