Choose the correct statements from the following. \(A\). All group \(16\) elements form oxides of general formula \(\mathrm{EO}_2\) and \(\mathrm{EO}_3\) where \(\mathrm{E}=\mathrm{S}, \mathrm{Se}, \mathrm{Te}\) and Po. Both the types of oxides are acidic in nature. \(B\). \(\mathrm{TeO}_2\) is an oxidising agent while \(\mathrm{SO}_2\) is reducing in nature. \(C\). The reducing property decreases from \(\mathrm{H}_2 \mathrm{~S}\) to \(\mathrm{H}_2 \mathrm{Te}\) down the group. \(D\). The ozone molecule contains five lone pairs of electrons.
