UPSC Prelims 2018— Question 4

**Concept and analysis:** The National Green Tribunal is a statutory judicial body created under the National Green Tribunal Act, 2010, with jurisdiction over specified environmental disputes and relief. The Central Pollution Control Board is a statutory pollution-control authority constituted under the Water Act, 1974 and entrusted with functions under the Air Act, 1981. Thus the distinction in the question is between an environmental adjudicatory forum and a regulatory/technical pollution-control institution. The question is testing precise UPSC-level identification rather than a broad association. The key is to distinguish the exact institutional, constitutional, historical, geographical, economic or scientific feature being asked. **Option-wise evaluation** **Option A:** Incorrect. It selects 1 only, but that combination does not match the verified statement-level assessment; it either includes a false statement or omits a true one. **Option B:** Correct. It selects statements 2; these are the statements supported by the relevant constitutional, economic, historical, scientific or geographical facts. **Option C:** Incorrect. It selects Both 1 and 2, but that combination does not match the verified statement-level assessment; it either includes a false statement or omits a true one. **Option D:** Incorrect. It selects Neither 1 nor 2, but that combination does not match the verified statement-level assessment; it either includes a false statement or omits a true one. **UPSC takeaway:** The safest way to solve this type of question is to anchor the answer in the defining feature of the concept and then test every option against that feature. Closely related institutions or terms are often used as distractors. In statement-based questions, do not judge the option as a whole before checking each statement independently. In factual questions, compare the wording of each option with the exact definition, location, institutional role, chronology or scientific property. The correct answer follows from that verification rather than from familiarity with a keyword.
