Oxidatio potential of Al, Cu,Zn and Ag are given and series of reaction . Identify the correct group pf reaction :
`E_(Al)^(0) = 1.66 V, E_(Cu)^(0) = -0.34 V`,
`E_(Zn)^(0) = 0.76 V, E_(Cu)^(0) = -0.8 V`

A

`AlCl_(3) + 3Ag to 3AgCl + Al`,
`CuSO_(4) + 2Ag to Ag_(2)SO_(4) + Al`
`ZnSO_(4) + 2Ag to Ag_(2)SO_(4) + Zn`,
`ZnSO_(4) + Cu to CuSO_(4), Zn`

B

`2AlCl_(3) + 3Zn to 3ZnCl_(2) + 2Al, `
`ZnCl_(2) + Cu to CuCl_(2) + Zn`
`CuSO_(4) + Zn to ZnSO_(4) + Cu`,
`3ZnSO_(4) + 2Al to Al_(2)(SO_(4))_(3)+ 3Zn`

C

`2AlCl_(3) + 3Cu to 3CuCl_(2)l + 2Al`,
`3ZnSO_(4) + 2Al to Al_(2)(SO_(4))_(3) + 3Zn`
`CuSO_(4) + 2Ag to Ag_(2)SO_(4) + 3Zn`
`2Al Cl_(3) + 3Zn to 3ZnCl_(2) + 2Al`

D

`3ZnSO_(4) + 2Al to Al_(2)SO_(4) + 3Zn`,
`CuSO_(4) + Zn to ZnSO_(4) + Cu`
`2AgNO_(3) + Cu to Cu(NO_(3))_(2) + 2Ag `
`3CuSO_(4) +2Al to Al_(2)(SO_(4))_(3) + 3Cu`
