The standard reduction potential for half reactions for four different elements. `A, B, C` and `D` are:
(i) `A_(2) + 2e^(-) rarr 2A^(-), E^(@) = + 2.85 V`
(ii) `B_(2) + 2e^(-) rarr 2B^(-), E^(@) = + 1.36 V`
(iii) `C_(2) + 2e^(-) rarr 2C^(-), E^(@) = + 1.06 V`
(iv) `D_(2) + 2e^(-) rarr 2D^(-), E^(@) = + 0.53 V`
The strongest oxidising reducing agents smong these :

Options

A. Would be `A` and `D` respectively
B. Would be `D` and `A` respectively
C. Would be `B` and `C` respectively
D. Cannot be ascertained from the given data as the species being subjected to ioxidation or reduction have not been indicated

Answer

A

Explanation

Strongest oxidising agent has higher reduction potential. Strongest reducing agent has lowest reduction potential.
