Solution

The correct option is B $P t | H_{2} (g) | N a O H (a q) | H g O (s) | H g (l) | P t$
$P t | H_{2} (g) | N a O H (a q) | H g O (s) | H g (l) | P t$

LHE reaction : $H_{2} (g) + 2 O H^{-} \to 2 H_{2} O (l) + 2 e^{-}$

RHE reaction : $H g O (s) + H_{2} O (l) + 2 e^{-} \to H g (l) + 2 O H^{-}$

Net cell reaction : $H g O (s) + H_{2} (g) \to H g (l) + H_{2} O$
