The Correct Option is D

Solution and Explanation


Step 1: Concept

Biodegradable polymers are materials that can be broken down by microorganisms into water, $CO_2$, and biomass.

Step 2: Meaning

Polylactic acid (PLA) is one of the most prominent and widely used biodegradable and bioactive thermoplastic aliphatic polyesters.

Step 3: Analysis

PLA is derived from renewable resources like corn starch or sugarcane and is explicitly used to create biodegradable plastic products like cups, cutlery, and packaging.

Step 4: Conclusion

Therefore, the statement that PLA cannot be used for such products is factually incorrect. Final Answer: (D)
