Given below are two statements:
Statement I: To address problem of climate change it is essential for the world to have 'Net Zero' carbon emissions by the year 2050.
Statement II: There is zero carbon emission associated with the production of gray-hydrogen.
In light of the above statements, choose the correct answer from the options given below:नीचे दो कथन दिए गए हैं:
कथन I: जलवायु परिवर्तन की समस्या के समाधान हेतु यह आवश्यक है कि विश्व वर्ष 2050 तक 'नेट जीरो' कार्बन उत्सर्जन प्राप्त कर ले।
कथन II: ग्रे-हाइड्रोजन के उत्पादन से जुड़ा कार्बन उत्सर्जन शून्य होता है।

Correct answer: C. Statement I is true but Statement II is falseकथन I सत्य है, किंतु कथन II असत्य है
Explanation
Statement I is true — the IPCC and the Paris Agreement pathway for limiting warming to 1.5°C require global net-zero CO₂ emissions by about 2050. Statement II is false: gray hydrogen is made by steam methane reforming of natural gas and releases large quantities of CO₂; it is green hydrogen (electrolysis using renewable power) that is carbon-free.कथन I सत्य है — IPCC तथा पेरिस समझौते के 1.5°C मार्ग के अनुसार लगभग 2050 तक वैश्विक नेट-जीरो CO₂ उत्सर्जन आवश्यक है। कथन II असत्य है: ग्रे-हाइड्रोजन प्राकृतिक गैस के स्टीम मीथेन रिफॉर्मिंग से बनती है और भारी मात्रा में CO₂ छोड़ती है; कार्बन-मुक्त तो ग्रीन हाइड्रोजन (नवीकरणीय बिजली से विद्युत अपघटन) होती है।More People, Development and Environment questions
