Concept:Understand the environmental impact of plastic waste and whether plastics are biodegradable.
Explanation:Assertion (A) states that plastic waste is a major environmental concern.
This is true because plastic waste pollutes land and oceans, harms wildlife, and accumulates in ecosystems.
Plastics take hundreds of years to decompose, so they persist in the environment for a very long time.
Reason (R) claims that plastics are biodegradable and break down quickly.
This is false because plastics are non-biodegradable materials.
They do not decompose quickly; instead, they remain as waste for decades or even centuries.
Therefore, the reason is incorrect and cannot explain the given assertion.
Hence, the correct choice is the one where (A) is true but (R) is false.
Answer:Option C: (A) is true but (R) is false.
