The standard EMF for the cell reaction, \[Zn+C{{u}^{2+}}\xrightarrow{{}}Cu+Z{{n}^{2+}}\] is 1.1 volt at \[25{}^\circ C.\] The EMF for the cell reaction, when \[0.1\,MC{{u}^{2+}}\] and \[0.1MZ{{n}^{2+}}\] solutions are used, at \[25{}^\circ C\] is

• A. 1.10 V              
• B. 0.10 V
• C. \[-1.10\text{ }V\]           
• D. \[-0.110\text{ }V\]
