UGC NET Questions (Paper – 1)

Statement D is the only wrong statement because open burning or dumping of e-waste releases toxic substances and is not environmentally safe. Statements A, B and C correctly describe what constitutes e-waste, the dangers of improper disposal and the need for recycling and proper management. Sustainable ICT practice emphasises minimising harm through responsible handling of discarded devices. Thus, the option that selects only D as wrong is correct.

Option A:
Option A is incorrect because it labels A and D as wrong. Statement A is true, as e-waste comprises various discarded electronic devices. Including a correct statement in the wrong set makes this combination invalid.

Option B:
Option B is incorrect because it groups B and D as wrong. While D is wrong, B is correct in noting the environmental and health risks of improper e-waste disposal. Mixing true and false statements prevents this option from being right.

Option C:
Option C is incorrect because it lists A, B and D as wrong statements. Both A and B correctly define e-waste and highlight associated hazards, so they should not be treated as wrong. Only D is incorrect.

Option D:
Option D is correct because it isolates D as the sole wrong statement. It reflects the scientific understanding that unsafe disposal practices harm people and ecosystems, and that responsible recycling and management are necessary.
