Solution
The correct option is B In the interior of the membrane
In
a cell membrane, the hydrophobic ends of phospholipid molecules in the outer
monolayer of the membrane are sandwiched between the hydrophilic heads of the
phospholipid bilayer and are not exposed to the environment.
So, the correct answer is 'In the interior of the membrane'.
