Li  occupies higher position  in  the electrochemical series of metals as compared to Cu since

A)  the standard reduction potential \[L{{i}^{+}}/Li\] is lower than that of \[C{{u}^{2+}}/Cu\]

B)  the standard reduction potential of \[C{{u}^{2+}}/Cu\]is lower than that of\[L{{i}^{+}}/Li\]

C)  the standard oxidation potential of \[Li/L{{i}^{+}}\] is lower than that of \[Cu/C{{u}^{2+}}\]

D)  Li is smaller in size as compared to Cu.
