Verified step by step guidance

Understand the structure of the plasma membrane: The plasma membrane is primarily composed of a bilayer of phospholipids, which provides a flexible matrix and creates a barrier to the passage of ions and molecules.

Identify the additional components of the plasma membrane: Besides phospholipids, the plasma membrane contains proteins, which are embedded within or attached to the lipid bilayer.

Explore the role of proteins in the plasma membrane: Proteins serve various functions such as transport, signal transduction, and acting as receptors. They are crucial for the membrane's functionality.

Consider other options: Nucleic acids, carbohydrates, and vitamins are not primary structural components of the plasma membrane. Nucleic acids are involved in genetic information storage, carbohydrates can be attached to proteins or lipids forming glycoproteins or glycolipids, and vitamins are essential nutrients but not structural components.

Conclude with the correct answer: Proteins are the correct answer as they are integral to the structure and function of the plasma membrane, alongside phospholipids.
