' A ' is a neutral organic compound $\displaystyle \left(\mathrm{M} . \mathrm{F}: \mathrm{C}_8 \mathrm{H}_9 \mathrm{ON}\right)$. On treatment with aqueous $\displaystyle \mathrm{Br}_2 / \mathrm{HO}^{(-)}$, ' A ' forms a compound ' B ' which is soluble in dilute acid. ' B ' on treatment with aqueous $\displaystyle \mathrm{NaNO}_2 / \mathrm{HCl}\left(0-5^{\circ} \mathrm{C}\right)$ produces a compound 'C' which on treatment with $\displaystyle \mathrm{CuCN} / \mathrm{NaCN}$ produces ' D '. Hydrolysis of ' D ' produces ' E ' which is also obtainable from the hydrolysis of 'A'. 'E' on treatment with acidified $\displaystyle \mathrm{KMnO}_4$ produces ' F '. ' F ' contains two different types of hydrogen atoms. The structure of ' A ' is
