D Correct answer
Explanation

Safer plasticizers with better biodegradability and fewer biochemical effects are being developed. Some such plasticizers are- Trimethyl citrate (TMC) that are compatible with PVC, Acetyl tributyl citrate (ATBC), compatible with PVC and vinyl chloride copolymers etc. The examples of non-biodegradable plasticizers are- Butanetriol trinitrate (BTTN), Trimethylolethane trinitrate (TMETN) etc. Hence, P and Q both are examples of biodegradable plasticizers.
