Answer 1

Right choice is (b) Most of the polysaccharides are sweet in taste and therefore are also called sugars

Easiest explanation: Polysaccharides are used to store food whereas most of the monosaccharides are used for instantaneous energy. Most of the monosaccharides and disaccharides are sweet in taste whereas polysaccharides don’t taste sweet. Starch can be digested whereas cellulose can’t be digested. Saccharides are also classified as ketose and aldose.
