Model Answer

(B) Greater accumulation of persistent waste in the environment

Non-biodegradable packaging cannot be broken down by biological processes and persists in the environment for a long time, causing serious accumulation of waste.

Explanation

The passage directly states: "Changes in packaging have resulted in much of our waste becoming non-biodegradable" and non-biodegradable substances "persist in the environment for a long time or may harm the various members of the eco-system." Options A, C, and D are unrelated to non-biodegradable waste disposal. Always link "non-biodegradable" → "persists" → "accumulates."
