One glycerol, one fatty acid and two phosphates

None of the above

Detailed explanation-1: -Phospholipids consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic.
Detailed explanation-2: -Phospholipids are composed of two fatty acids esterified to each of two carbon atoms of a glycerol molecule (sn-1 and sn-2) and one polar head group attached via a phosphate linkage to the third carbon atom (sn-3).
Detailed explanation-3: -A phospholipid is a type of lipid molecule that is the main component of the cell membrane. Lipids are molecules that include fats, waxes, and some vitamins, among others. Each phospholipid is made up of two fatty acids, a phosphate group, and a glycerol molecule.
