1.Phospholipid contains fatty acids and glycerol in addition to phosphoric acid , nitrogen base and other substituents
Phospholipid are 3 types mainly-. Phosphoglycerides, phosphoinositides and phosphosphingosides.
Hence the common backbone is phospholipid.
(C) option is correct.
2. Steroids are made by fusion of carbon rings and not by fatty acids hence option (e) is correct.
