d. lipid rafts

Explanation:

It is thought by some investigators that cholesterol and sphingolipids self-assemble into microdomains within the plasma membrane that are more gelated and highly ordered than surrounding regions that contain primarily phospholipids. It is hypothesized that certain proteins tend to concentrate in these so-called lipid rafts, thereby organizing the membrane into functional compartments.
