How is the plasma membrane of a cell organized?
question 15 options:

one layer of phospholipids, through which proteins freely move

one layer of phospholipids, which are laid out end-to-end, with a hydrophobic tail touching a hydrophilic head

two layers of phospholipids, each of which has its hydrophilic side turned inward

two layers of phospholipids, with their polar hydrophilic heads facing away from each other

The correct answer is two layers of phospholipids,with their polar hydrophilic heads facing away from each other.

Explanation:

The plasma membrane of a cell contain lipid bilayer.Each monolayer contain phospholipids.The hydrophobic tails of the phospholipid of both the monolayers faces each other in the hydrophobic region where as the hydrophilic heads of the phospholipid molecules of both the monolayers are oriented away from each other.
