Statement Based

Given below are two statements

Statement I : Global Warming Potential (GWP) is a measure of how much energy the emissions of 1 tonne of a gas will absorb over a given period of time, relative to the emissions of 1 tonne of carbon dioxide ($CO_2$).

Statement II : A gas with a smaller GWP warms the Earth more compared to $CO_2$ over that time period.

In the light of the above statements, choose the most appropriate answer from the options given below :

नीचे दो कथन दिए गए हैं

कथन I : ग्लोबल वार्मिंग पोटेंशियल (GWP) इस बात का माप है कि किसी गैस के 1 टन उत्सर्जन से एक निश्चित समय अवधि में कार्बन डाइऑक्साइड ($CO_2$) के 1 टन उत्सर्जन की तुलना में कितनी ऊर्जा अवशोषित होगी।

कथन II : छोटी GWP वाली गैस उस समयावधि में $CO_2$ की तुलना में पृथ्वी को अधिक गर्म करती है।

Both Statement I and Statement II are true कथन I और कथन II दोनों सत्य हैं Both Statement I and Statement II are false कथन I और कथन II दोनों असत्य हैं Statement I is true but Statement II is false कथन I सत्य है लेकिन कथन II असत्य है Statement I is false but Statement II is true कथन I असत्य है लेकिन कथन II सत्य है
