    Option A) macromolecules

    Explanation:

    The cell membrane is selectively permeable due to its molecular structure, only small molecules such as nutrients like Sodium, Potassium, glucose, oxygen and carbondioxide etc pass through them. Macromolecules such as carbohydrates, proteins and lipids are bigger in size so they cannot pass through cell membrane.
