Consider the following standard reduction potentials:-
`{:(Fe^(2+)+2e^(-)hArrFe,,,E^(@) =- 0.41V),(Ag^(+)+e^(-)hArrAg,,,E^(+)=0.80V),(O_(2)+2H_(2)O+4e^(-)hArr4OH^(-),,,E^(@)=0.40V):}`
What would happens if a block of silver metal is connected to a buried iron pipe via a wire:-

A

The silver metal would corrode, a current would be produced in the wire, and `O_(2)` would be reduced on the surface of the iron pipe.

B

The silver metal would corrode, a current would be produced in the wire, and `Fe^(2+)` would be reduced on the surface of the iron pipe.

C

The iron pipe would corrode, a current would be produced in the wire, and `Ag^(+)` would be reduced on the surface of the silver metal.

D

The iron pipe would corrode, no current would be produced in the wire, and `O_(2)` would be reduced on the surface of the iron pipe.
