The standard electrode potential \[\left( E{}^\circ \right)\] for \[OC{{l}^{-}}/C{{l}^{-}}\] and \[C{{l}^{-}}/\frac{1}{2}C{{l}_{2}}\] respectively are 0.94 V and \[-1.36\text{ }V\]. The \[E{}^\circ \] value for \[OC{{l}^{-}}/\frac{1}{2}C{{l}_{2}}\] will be

• A. \[-0.42\,\,V\]
• B. \[-2.20\,\,V\]
• C. 0.52 V                           
• D. 1.04 V
