Polar stratospheric clouds facilitate the formation of :

Given below are two statements :

Statement I : In 'Lassaigne's Test', when both nitrogen and sulphur are present in an organic compound, sodium thiocyanate is formed.

Statement II : If both nitrogen and sulphur are present in an organic compound, then the excess of sodium used in sodium fusion will decompose the sodium thiocyanate formed to give NaCN and Na₂S.

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

(C₇H₅O₂)₂ $$\buildrel {hv} \over \longrightarrow $$ [X] $$\to$$ 2C₆H₅ + 2CO₂

Consider the above reaction and identify the intermediate 'X'

Consider the above reaction sequence and identify the product B.
