Answer: (C)

A- p, B- r, C- s, D- t

Phosphatidylcholine (lecithin) is a glycerophospholipid and is a component of many membranes. It has two fatty acids joined to the first and second carbons of glycerol in ester linkage and choline group attached through a phosphodiester linkage to the third carbon. Cholesterol is amphipathic sterol with a polar head group and a nonpolar steroid nucleus and the hydrocarbon side chain. The chloroplast is plastid with chlorophyll pigment and serves as a site for photosynthesis. Anthocyanin is water soluble pigment that impart red/blue/purple color to leaves and flowers. Thus, the correct answer is option C.
