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 $\displaystyle \mathrm{Na}_2 \mathrm{~S}$.
In the light of the above statements, choose the most appropriate answer from the options given below :
Official answer
(1)
