UGC NET Questions (Paper – 1)

The 3R hierarchy gives priority to options that prevent or minimise waste at source. "Reduce" comes first, as using less material and energy avoids waste altogether. "Reuse" comes next, because using an item again extends its life before it becomes waste. "Recycle" is still useful but comes last among the three because it requires collection and processing. Hence, the preferred order is Reduce → Reuse → Recycle.

Option A:
Option A is incorrect because starting with recycle ignores the greater benefit of reducing consumption. Recycling helps, but it does not avoid production in the first place.

Option B:
Option B is correct as it lists reduction, then reuse, then recycling. This sequence is promoted in policy and education for waste minimisation.

Option C:
Option C is incorrect; putting reuse first still overlooks the importance of avoiding unnecessary items. Prevention is better than reuse.

Option D:
Option D is incorrect because it begins with recycle again. While both reduce and reuse appear, the order does not reflect the standard 3R hierarchy.
