Answer:
The correct order would be a hydrophilic head, hydrophobic tail, hydrophobic tail, and hydrophilic head.
The plasma membrane is a lipid bilayer, that is, a layer formed of two layers of phospholipids.
A phospholipid is made up of two parts; hydrophilic polar heads and hydrophobic lipid tail.
The two layers are arranged in such a way that the hydrophilic parts are present outwards and the hydrophobic tails are sandwiched between the polar heads of two layers.
Thus, the order would be a hydrophilic head, hydrophobic tail, hydrophobic tail, and hydrophilic head.
