Answer 1

The correct answer is "is a stabilizing component of the plasma membranes and is the parent molecule of steroid hormones".

Cholesterol makes the plasma membranes stable by slightly immobilizing it and making it less permeable to molecules. This, in turn, results to a cell membrane with decreased fluidity and decreased permeability but with increased stability.
