Why do cholesterol molecules integrate more readily into membranes made of glycerophospholipids compared with those made mostly of triacylglycerols?

• A. Cholesterol is polar like glycerophospholipids, making them integrate more readily into membranes composed primarily of glycerophospholipids, rather than those made up mostly of triacylglycerols, which are nonpolar.
• B. Cholesterol has both polar and nonpolar regions like glycerophospholipids, making them integrate more readily into membranes composed primarily of glycerophospholipids, rather than those made up mostly of triacylglycerols, which are nonpolar.
• C. Cholesterol is nonpolar like glycerophospholipids, making them integrate more readily into membranes composed primarily of glycerophospholipids, rather than those made up mostly of triacylglycerols, which are polar.
• D. Cholesterol is nonpolar like glycerophospholipids, making them integrate more readily into membranes composed primarily of glycerophospholipids, rather than those made up mostly of triacylglycerols, which have both polar and nonpolar regions.
