Statement Based +4 −1

Given below are two statements

Statement (I) : $\text{LD}_{50}$ is the dose or amount of pesticide which would kill $50\%$ of the test animals if ingested or absorbed through skin.

Statement (II) : $\text{LT}_{50}$ is the concentration of a single pesticide which is lethal to $50\%$ of the test animals if ingested or absorbed through skin.

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

नीचे दो कथन दिए गए हैं

कथन (I) : $\text{LD}_{50}$ कीटनाशक की वह खुराक या मात्रा है जो परीक्षण जंतुओं के निगलने या त्वचा के माध्यम से अवशोषित होने पर $50\%$ को मार देती है।

कथन (II) : $\text{LT}_{50}$ किसी एकल कीटनाशक की वह सांद्रता है जो परीक्षण जंतुओं के निगलने या त्वचा के माध्यम से अवशोषित होने पर $50\%$ के लिए घातक होती है।

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

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।
