Consider the following reactions, {\C}_2 {\H}_2 {───\xrightarrow↙\stackrel{\text{ red hot iron tube }{500^oC}} {A} A {─────────\xrightarrow↙\stackrel{\text{ conc. }{70^oC} {\HNO}_3 \text{, conc. } {\H}_2 {\SO}_4} {\70} B \stackrel{ {\LiAlH}{──────▶}_4} {\C}_6 {\H}_5- {\N}= {\N}- {\C}_6 {\N}_5 A and B are

Correct Answer is : A=C6H6,B=C6H5NO2

A= {\C}_2 {\H}_4, B= {\C}_6 {\H}_6

A= {\C}_2 {\H}_6, B= {\C}_6 {\H}_5 {\NH}_2

A= {\C}_2 {\H}_4, B= {\C}_6 {\H}_5 {\NH}_2

A= {\C}_6 {\H}_6, B= {\C}_6 {\H}_5 {\NO}_2
