Major greenhouse gases list – UGC NET Question

Greenhouse gases are those that can absorb and emit infrared radiation, contributing to the greenhouse effect. Carbon dioxide from fossil fuels and deforestation, methane from agriculture and waste, and nitrous oxide from fertilisers are key anthropogenic drivers of current climate change. They have increased significantly in concentration since the industrial revolution.

Option A:
Option A is incorrect because nitrogen, oxygen and argon are major components of air but are not strong greenhouse gases under normal conditions.

Option B:
Option B is correct as it lists three important long-lived greenhouse gases recognised in international climate agreements.

Option C:
Option C is incorrect since neon, helium and krypton are inert gases with negligible greenhouse effect.

Option D:
Option D is incorrect because hydrogen, neon and argon are not principal contributors to observed warming.
