B Correct answer
Explanation

Disposal of plastics is a major problem because they are non-biodegradable - they cannot be broken down by natural processes. Unlike biodegradable materials that decompose over time, plastics persist in the environment for hundreds of years. While some plastics can be reused, the core issue is their non-biodegradable nature.
