Which expression represents the cell potential $(E_{cell})$?

At $25^\circ C$,$1 \, atm$ of gas $X$ is bubbled through a solution containing $1 \, M$ $Y^-$ and $1 \, M$ $Z^-$. If the reduction potential order is $Z > Y > X$,then:

For the reaction taking place in the cell:
$Pt_{(s)} | H_{2(g)} | H^{+}_{(aq)} || Ag^{+}_{(aq)} | Ag_{(s)}$
$E_{Cell}^0 = +0.5332 \ V$.
The value of $\Delta_f G^0$ in $kJ \ mol^{-1}$ (nearest integer) is:

These are physical properties of an element:
$(A)$ Sublimation enthalpy
$(B)$ Ionisation enthalpy
$(C)$ Hydration enthalpy
$(D)$ Electron gain enthalpy
The total number of the above properties that affect the reduction potential is $......$ .

Which from the following is the correct relationship between standard Gibbs energy change and standard cell potential?
