The standard reduction potentials of ${\mathrm{Zn}}^{2+}\mid \mathrm{Zn}$ ${\mathrm{Cu}}^{2+}\mid \mathrm{Cu}\text{ and }{\mathrm{Ag}}^{+}\mid$Ag are respectively – 0.76, 0.34 and 0.8V. The following cells were constructed 

A) $\mathrm{Zn}/{\mathrm{Zn}}^{2+}//{\mathrm{Cu}}^{2+}/\mathrm{Cu}$ B) $\mathrm{Zn}/{\mathrm{Zn}}^{2+}//{\mathrm{Ag}}^{+}/\mathrm{Ag}$ C) $\mathrm{Cu}/{\mathrm{Cu}}^{2+}//{\mathrm{Ag}}^{+}/\mathrm{Ag}$  What is the correct order of ${\mathrm{E}}_{\text{cell }}^0$ of these cells ?
