Question

Which of the following is a biodegradable polymer?

• A. Nylon 6
• B. Nylon 6,6
• C. Both Nylon 6 and Nylon 6,6
• D. Viscose rayon

Hint:

Nylons are synthetic polyamides that resist degradation, while viscose rayon is made from cellulose.

Answer 1

The Correct Option is D

Step 1: Eliminate
Both nylons are synthetic and persist in the environment, so (A), (B) and (C) are out.

Step 2: Remaining Option
Viscose rayon is made from cellulose, which microbes can degrade.

Step 3: Conclusion
Option (D) is correct.

Final Answer:
Only viscose rayon is biodegradable here. \[ \boxed{\text{(D) }\text{Viscose rayon}} \]
