Correct answer: none of them

Fats, steroids and waxes are not polar in any way. They are, in fact, completely hydrophobic and, therefore, not soluble. That makes of the options (a) and (b) false statements.

The option (c) is correct only for steroids. Fats and waxes are only storage lipids and not membrane lipids.
