${\mathrm{E}}_{{\mathrm{Cu}}^{2+}/\mathrm{Cu}}^{°}=+0.34\mathrm{V};{\mathrm{E}}_{{\mathrm{Zn}}^{2+}/\mathrm{Zn}}^{°}-0.76\mathrm{V}$
Identify the incorrect statement from the options below for the above cell

If ${\mathrm{E}}_{\mathrm{ext}}<1.1\mathrm{V}$ , Zn dissolves at anode and Cu deposits at cathode 

If ${\mathrm{E}}_{\mathrm{ext}}=1.1\mathrm{V}$ , no flow of electrons or current occurs 
 

If  ${\mathrm{E}}_{\mathrm{ext}}>1.1\mathrm{V}$ Zn dissolves at Zn electrode and Cu deposits at Cu electrode 
 

If ${\mathrm{E}}_{\mathrm{ext}}>1.1\mathrm{V}$ electrons flow from Cu to Zn
