Which one of the following is the product $(\mathrm{Z})$ formed at the end of the given reaction:

$$\begin{aligned} & \text { Propan-1-ol }+\mathrm{SOCl}_2 \rightarrow[\mathrm{X}] \\ & {[\mathrm{X}]+\mathrm{HC} \equiv \mathrm{C}-\mathrm{Na} \rightarrow[\mathrm{Y}]} \\ & {[\mathrm{Y}]+\mathrm{H}_2 \mathrm{SO}_4 / \mathrm{HgSO}_4, 330 \mathrm{~K} \rightarrow[\mathrm{Z}]} \end{aligned}$$

Choose the incorrect statement.

An organic compound " A " reacts with $\mathrm{Zn} / \mathrm{Hg}$ / Conc. HCl to form p-Xylene. It reduces Tollen's reagent and on oxidation with $\mathrm{KMnO}_4 / \mathrm{H}^{+}$it yields 1, 4-benzenedicarboxylic acid. Identify compound A.

Two statements, one Assertion (A) and the other Reason (R) are given. Choose the correct option.

Assertion: Compound $[\mathrm{X}]$ reacts with Hydrazine in presence of $\mathrm{KOH} /$ Glycol to form the product $[\mathrm{Y}]$.

Reason: Reduction reaction occurs and Carbonyl group is reduced to Methylene group.
