Answer 1

Answer: (B)

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

Starch a storage polysaccharides of plants is made up of amylose (straight chain of glucose) and amylopectin (branched chain of glucose).

Lignin is a polymer of coniferyl alcohol and other aromatic alcohols.

Chitin is a polymer which forms cell wall in fungi and arthropods. It is made up of acetyl glucosamine units.

Proteins are polymers of amino acids. In proteins amino acids are joined together by peptide bonds.

So, the correct answer is 'A - q, B - r, C - s, D - t'
