Answer:
The correct option is <em>B. Cholesterol is non-polar.</em>
Explanation:
Cholesterol is a non- polar substance and due to this property it is an active part of the cell membrane. Cholesterol molecules help to maintain the stability of a cell. When the temperatures are high, cholesterol stops the cell membrane from crystallization. When the temperatures are low, cholesterol reduces the packaging of molecules of phospholipids. As a result, fluid phase is archived by the cell membrane.
