Show answer & explanation
Correct answer: B. Liquid Hydrogen (LH)तरल हाइड्रोजन (एल एच)
Explanation
CNG and LPG are fossil fuels. Liquid hydrogen is a fuel that is not of fossil origin, and PET is a plastic (a polymer), not a fuel at all, so neither is a fossil fuel. The board accepted both options 2 and 3.सी.एन.जी. और एल.पी.जी. जीवाश्म ईंधन हैं। तरल हाइड्रोजन जीवाश्म मूल का ईंधन नहीं है और PET एक प्लास्टिक (बहुलक) है, ईंधन ही नहीं, इसलिए दोनों जीवाश्म ईंधन नहीं हैं। बोर्ड ने विकल्प 2 और 3 दोनों को मान्य किया।More Environmental Studies (EVS) questions
