During halogen test, sodium fusion extract is boiled with concentrated HNO_3 to

A student has been given a compound " $x$ " of molecular formula- $\mathrm{C}_{6} \mathrm{H}_{7} \mathrm{~N}$. ' $x$ ' is sparingly soluble in water. However, on addition of dilute mineral acid, ' $x$ ' becomes soluble in water. ' $x$ ' when treated with $\mathrm{CHCl}_{3}$ and $\mathrm{KOH}($ alc $)$, ' $y$ ' is produced. ' y ' has a specific unpleasant smell. On treatment with benzenesulphonyl chloride, ' $x$ ' gives a compound ' $z$ ' which is soluble in alkali. The number of different " $H$ " atoms present in ' $z$ ' is:-

Given below are two statements : Statement I: Compound $(X)$, shown below, dissolves in $\mathrm{NaHCO}_{3}$ solution and has two chiral carbon atoms  Statement II: Compound $(\mathrm{Y})$, shown below, has two carbons with $\mathrm{sp}^{3}$ hybridization, one carbon with $\mathrm{sp}^{2}$ and one carbon with sp hybridization  In the light of the above statements, choose the correct answer from the options given below :
