    The standard reduction electrode potentials of four elements are                 \[A=-0.250\,\,V\]             \[B=-0.136\,V\]                 \[C=-0.126\,\,V\]             \[D=-0.402\,\,V\]                 The element that displaces A from its compounds is

    A)                 B            

    B)                 C

    C)                 D            

    D)                 None of these

    Correct Answer: B

    Solution :

                    A is displace from D because D have a \[{{E}^{o}}=-0.402\,\,V\].
