Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: Biomass is considered as carbon neutral.
Reason R: The amount of carbon they emit is equal to the amount of carbon they have consumed during their life-time.
In light of the above statements, choose the most appropriate answer from the options given below:नीचे दो कथन दिए गए हैं, एक को अभिकथन (A) और दूसरे को कारण (R) कहा गया है
अभिकथन (A): जैव-भार (biomass) को कार्बन-निरपेक्ष (carbon neutral) माना जाता है।
कारण (R): वे जितनी मात्रा में कार्बन उत्सर्जित करते हैं, वह उतनी ही होती है जितनी उन्होंने अपने जीवनकाल में ग्रहण की होती है।
उपर्युक्त कथनों के आलोक में, नीचे दिए गए विकल्पों में से सर्वाधिक उपयुक्त उत्तर चुनिए:

Show answer & explanation
Correct answer: A. Both A and R are correct and R is the correct explanation of A(A) और (R) दोनों सही हैं और (R), (A) की सही व्याख्या है
Explanation
Biomass is called carbon neutral because the carbon dioxide released when it is burnt is the same carbon that the plant absorbed from the atmosphere through photosynthesis while growing, so there is no net addition to atmospheric carbon. R therefore states exactly the reason why A holds. Hence both A and R are correct and R is the correct explanation of A.जैव-भार को कार्बन-निरपेक्ष इसलिए कहा जाता है क्योंकि उसके दहन पर निकलने वाली कार्बन डाइऑक्साइड वही कार्बन है जिसे पौधे ने बढ़ते समय प्रकाश-संश्लेषण द्वारा वायुमंडल से ग्रहण किया था, अतः वायुमंडलीय कार्बन में कोई शुद्ध वृद्धि नहीं होती। इस प्रकार (R) ठीक वही कारण बताता है जिससे (A) सत्य है। अतः (A) और (R) दोनों सही हैं और (R), (A) की सही व्याख्या है।More People, Development and Environment questions
