The correct option is D. (Two back-to-back phospholipid layers with the polar heads facing out on both sides)
Explanation:
The plasma membrane creates a barrier between the interior part of the cell and the cytoplasm. It is consisting of proteins and phospholipids and bi-layered in nature. Phospholipids are known as the main component of the plasma membrane.
Phospholipids are composed of alcohol and fatty acids and they are arranged in a specific manner. Each phospholipid molecule contains a water-hating tail that is hydrophobic in nature and a water-loving head which is hydrophilic in nature and the polar heads face the outside.
