Which from following polymers is biodegradable?

Step-by-step solution

Nylon 2-nylon 6 is the biodegradable polymer among the options. While nylon 6 and nylon 6,6 are synthetic polyamides with poor biodegradability, and high-density polyethylene exhibits high resistance to degradation, nylon 2-nylon 6 is a copolymer of glycine and aminocaproic acid. The amide linkages derived from these amino acids render it susceptible to enzymatic hydrolysis, enabling biodegradation. The biodegradable polymer is therefore C .
