Standard potentials (E^∘) for some half-reactions are given below:
(i) Sn^4++2 e^-→Sn^2+ ; E^o=+0.15  V
(ii) 2 Hg^2++2 e^-→Hg_2^2+ ; E^o=+0.92  V
(iii) PbO_2+4 H^++2 e^-→Pb^2++2 H_2O ; E^o=+1.45  V
Based on the above, which one of the following statements is correct ?
(a) Sn^4+ is a stronger oxidising agent than Pb^4+
(b) Sn^2+ is a stronger reducing agent than Hg_2^2+
(c) Hg^2+ is a stronger oxidising agent than Pb^4+
(d) Pb^2+ is a stronger reducing agent than Sn^2+
