The standard reduction potential values of some of the p-block ions are given below. Predict the one with the strongest oxidising capacity.

A

$$E_{Pb^{4+}/Pb^{2+}}^{\ominus}=+1.67 V$$

B

$$E_{Sn^{4+}/Sn^{2+}}^{\ominus}=+1.15 V$$

C

$$E_{Al^{3+}/Al}^{\ominus}=-1.66 V$$

D

$$E_{Tl}^{\ominus}/Tl/2.26 V$$
