Solution

The correct option is B Phospholipid bilayer with embedded proteins
The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer. Each phospholipid molecule has a head and two tails. The head “loves” water (hydrophilic) and the tails “hate” water (hydrophobic).
