Classes: A) Polysaccharides B) Disaccharides C) Monosaccharides
A) I-A; II-B; III-C
B) I-B; II-A; III-C
C) I-C; II-A; III-B
D) I-C; II-B; III-A

Answer 1

Carbohydrates are classified according to the number of saccharides they contain. Monosaccharide are called as such for containing only one saccharide like glucose. Disaccharides for containing two saccharide units for instance sucrose which is formed from two glucose molecules.
