Carbohydrate-containing layer at the surface of the plasma membrane
A
glycocalyx
B
cholesterol
C
triglyceride
D
phospholipid
Explanation: 

Detailed explanation-1: -Likewise, the carbohydrate portions of glycolipids are exposed on the outer face of the plasma membrane. Consequently, the surface of the cell is covered by a carbohydrate coat, known as the glycocalyx, formed by the oligosaccharides of glycolipids and transmembrane glycoproteins (Figure 12.13).

Detailed explanation-2: -The glycocalyx is a polysaccharide or carbohydrate-rich lining that envelopes the outer layer of a cell. The exact glycocalyx structure is still not known. However, biochemical analysis has revealed that components of the glycocalyx are proteoglycans, glycosaminoglycans, glycoproteins, and associated plasma proteins.

Detailed explanation-3: -Glycocalyx is a surface layer that covers the cell membrane of many bacteria, epithelial cells or other cells. It is made up of proteoglycans, glycoproteins and glycolipids.
