H_{2}O_{2}  can oxides H_{2}S to S

KMnO_4 and K_2Cr_2O_7 cannot be further oxidised as they already contain the maximum oxidation state of the central metal atom i.e. Mn^{7+} and Cr^{6+} respectively

Pb^{2+}cannot be oxidised into Pb^{4+} due to inert pair effect.

Therefore, option(1) is correct.
