General KnowledgeGeography

- BThey do not get released into water and food.
- CThey do not have any biochemical synthesis activity.
- DThey are harmless to humans.
Explanation
The central environmental problem with plastics is that they are non-biodegradable: microorganisms cannot break down their long polymer chains, so plastic waste persists in the environment for centuries. They do get released into water and food (as microplastics) and they are not harmless to humans. The answer is (A).
