Best answer
Correct choice is (a) Mannoprotein

Best explanation: The outer layer of the cell wall is composed of mannoprotein. It is a glycoprotein that accounts for 25 – 50 % of the cell wall. Mannoproteins are essential in the cell wall for the survival of the cell. They play an important role as antigenic determinants.
