What is the hybridisation state(s) of the atoms in $\underset{¯}{\mathrm{X}}$ formed in the following reaction?

$\underset{\text{ (Vapours) }}{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}}\frac{\text{ Conc. }{\mathrm{H}}_2{\mathrm{SO}}_4}{413 \mathrm{K}}\underset{¯}{\mathrm{X}}$

Given data:
It is given to identify the hybridization state(s) of the atoms in $\underset{¯}{\mathrm{X}}$ formed in the following reaction.
Explanation:

Hence, the correct option is option (A) $s{p}^3 only$.
