<u>Answer</u>: C) Hydrophobic interior, hydrophilic exterior
<u>Explanation</u>:
- The <em>plasma membrane</em> of the cell defines its boundary and separates its internal components from the external environment.
- The basic components of the plasma membrane include phospholipids, carbohydrates, proteins, and cholesterol.
- The plasma membrane is a phospholipid bilayer, with <em>hydrophobic</em> tails of the phospholipid projecting <em>inwards</em> and the <em>hydrophilic</em> exterior in contact with the external environment.
- <em>Due to this, the plasma membrane has a hydrophobic interior and hydrophilic exterior. </em>
