Verified by Experts

The correct Answer is:
D
The Cell involves the following reactions
`NaClrarrNa^(+)+Cl^(-)`
At anode : `2Cl^(-)-2e^(-)rarr2ClrarrCl_(2)`
At cathode : `Na^(+)+e^(-)rarrNa`
`Na+Hg rarr` Na amalgam
At anode : Na amalgam `rarr Na^(+)+Hg+e^(-)`
At cathode : `2H_(2)O + 2e^(-)rarrH_(2)uarr+2OH^(-)`
