Answer:
Phosphoglyceride.
Step-by-step explanation:
The cell membrane or plasma membrane is made up of lipid bilayer and proteins may be inserted or spans the membrane bilayer. The carbohydrate moieties are also present in association with lipids and proteins.
The phosphoglycerides are the most class of phospholipid present in plasma membrane. The phosphoglycerides consists of lipid bilayer linked with the hydroxyl group and the phosphate group is attached with the polar head group. The phosphate group attaches with the third carbon atom of the glycerol.
Thus, the correct answer is option (1).
