In the given reaction scheme, P is a phenyl alkyl ether, Q is an aromatic compound; R and S are the major products.

$\mathrm{P}\stackrel{\mathrm{HI}}{\to }\mathrm{Q}\underset{\left(\mathrm{iii}\right) {\mathrm{H}}_3{\mathrm{O}}^{+}}{\overset{\stackrel{\left(\mathrm{i}\right) \mathrm{NaOH}}{\left(\mathrm{ii}\right) {\mathrm{CO}}_2}}{\to }}\mathrm{R}\underset{\left(\mathrm{ii}\right) {\mathrm{H}}_3{\mathrm{O}}^{+}}{\overset{\left(\mathrm{i}\right) {\left({\mathrm{CH}}_3\mathrm{CO}\right)}_2\mathrm{O}}{\to }}\mathrm{S}$

The correct statement about S is
