Consider the following four electrodes: `A=Cu^(2+)(0.0001M)//Cu_((s))` `B=Cu^(2+)(0.1M)//Cu_((s))` `C= Cu^(2+)(0.01M)//Cu_((s))` `D=Cu^(2+)(0.001M)//C
Consider the following four electrodes:
`A=Cu^(2+)(0.0001M)//Cu_((s))`
`B=Cu^(2+)(0.1M)//Cu_((s))`
`C= Cu^(2+)(0.01M)//Cu_((s))`
`D=Cu^(2+)(0.001M)//Cu_((s))`
If the standard reduction potential of `Cu^(+2)//Cu` is `+0.34V`, the reduction potentials (in volts) of the above electrodes follow the order
A. `AgtDgtCgtB`
B. `BgtCgtDgtA`
C. `CgtDgtBgtA`
D. `AgtBgtCgtD`
