$S{O_2} + \frac{1}{2}{O_2} \to S{O_3} + y\,kcal$
Find out the heat of formation of $S{O_2}$
Statement $(I)$ : The oxidation state of an element in a particular compound is the charge acquired by its atom on the basis of electron gain enthalpy consideration from other atoms in the molecule.
Statement $(II)$ : $\mathrm{p} \pi-\mathrm{p} \pi$ bond formation is more prevalent in second period elements over other periods.
In the light of the above statements, choose the most appropriate answer from the options given below :

$C{H_3}C{H_2}C{H_2}Br\xrightarrow{{KOH(alc)}}(A)\xrightarrow{{HBr}}(B)\xrightarrow{{KOH\,(aq.)}}(C),$
$(A)$ Sublimation enthalpy
$(B)$ Ionisation enthalpy
$(C)$ Hydration enthalpy
$(D)$ Electron gain enthalpy
