Built around the concept in “Which gas is greenhouse gas?”, this bilingual General Science item checks whether a learner can connect a scientific term with its exact property, mechanism or function. The verified answer is Carbon dioxide.
Option C, Carbon dioxide, matches the evidence in the stem. Carbon dioxide (CO₂) is a major greenhouse gas that traps heat in the atmosphere. The alternatives Nitrogen, Hydrogen and Oxygen are legitimate scientific terms, but each belongs to a different function, property, material or context.

General Science covers basic concepts in Physics, Chemistry, Biology, and Earth Science. It is an important section in competitive exams like SSC CGL, UPSC Prelims, Railway NTPC, and Defence exams. Questions include scientific laws, inventions, human body systems, chemical reactions, and everyday science phenomena. NCERT Science books from Class 6 to 10 are recommended.
Newton's Three Laws of Motion: 1) First Law (Law of Inertia) - An object remains at rest or in uniform motion unless acted upon by an external force. 2) Second Law - Force equals mass times acceleration (F=ma). 3) Third Law - For every action there is an equal and opposite reaction. These laws are fundamental to Physics and frequently asked in SSC CGL, Railway, and NDA exams.
