Solution

The correct option is B

False


A series in which metals are arranged in the decreasing order of their reactivity is called reactivity series. The arrangement of metals as per reactivity series is: K > Na > Ca > Mg > Al > Zn > Fe > Ni > Sn > Pb > H > Cu > Ag > Au. Copper is less reactive than the nickel. Therefore, copper will not displace nickel from its salt.
