Statement $I$: Tropolone is an aromatic compound and has $8 \pi$ electrons.
Statement $II$: $\pi$ electrons of $ > C = O$ group in tropolone is involved in aromaticity.
In the light of the above statements, choose the correct answer from the options given below:

$C(s) + {O_2}(g) \to C{O_2}(g),\Delta H = - 394\,kJ$
$2{H_2}(g) + {O_2}(g) \to 2{H_2}O(l),\,\Delta H = 568\,kJ$
$C{H_4}(g) + 2{O_2}(g)\,\, \to \,\,C{O_2}(g) + 2{H_2}O(l)$ $\Delta H = - 892\,kJ$ Heat of formation of $C{H_4}$ is.....$kJ$
