B. `E_(C^(-)|C_(2))^(0) lt E_(B^(-)|B_(2))^(0) lt E_(A^(-)|A_(2))^(0) lt E_(D^(-)|D_(2))^(0)`
C. `E_(C^(-)|C_(2))^(0) lt E_(B^(-)|B_(2))^(0) gt E_(A^(-)|A_(2))^(0) gt E_(D^(-)|D_(2))^(0)`
D. `E_(C^(-)|C_(2))^(0) gt E_(B^(-)|B_(2))^(0) lt E_(A^(-)|A_(2))^(0) lt E_(D^(-)|D_(2))^(0)`

Answer

3

Explanation

Oxidation potential `prop` reducing strength, order of standard reductiion potential `D_(2)//D^(-) lt A_(2)//A^(-) lt B_(2)//B^(-) lt C_(2)//C^(-)` Order of standard oxidation potential `D_(2)//D^(-)gtA_(2)//A^(-)gtB_(2)//B^(-)gtC_(2)//C^(-)`
