Statement Based

Given below are two statements

Statement (I) : The greenhouse effect is retention of heat in the lower atmosphere due to absorption and re-radiation by clouds and certain gases.

Statement (II) : Long-wave thermal solar radiation received from the sun passes through the atmosphere with little or no interference and warms the earth's surface.

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

नीचे दो कथन दिए गए हैं

कथन (I) : ग्रीनहाउस प्रभाव बादलों और कुछ गैसों द्वारा अवशोषण और पुनर्विकिरण के कारण निचले वायुमंडल में ऊष्मा का रुकना है।

कथन (II) : सूर्य से प्राप्त होने वाला दीर्घ-तरंग तापीय सौर विकिरण बहुत कम या बिना किसी रुकावट के वायुमंडल से होकर गुजरता है और पृथ्वी की सतह को गर्म करता है।

उपर्युक्त कथनों के आलोक में, नीचे दिए गए विकल्पों में से सबसे उपयुक्त उत्तर चुनें:

Both Statement (I) and Statement (II) are correct कथन (I) और कथन (II) दोनों सही हैं Both Statement (I) and Statement (II) are incorrect कथन (I) और कथन (II) दोनों गलत हैं Statement (I) is correct but Statement (II) is incorrect कथन (I) सही है लेकिन कथन (II) गलत है Statement (I) is incorrect but Statement (II) is correct कथन (I) गलत है लेकिन कथन (II) सही है
