Answer:
The correct answer is beaker B.
Given that,
Beaker,
A=ZnSO4
B=AgNO3
C=FeSO4
When copper pieces added in each beaker, only less reactive solution will be displaced by Cu.
According to reactivity series Cu is more reactive than silver and less reactive than Zn and Fe.
2Cu+2AgNO3→Cu(NO3)2+2Ag
Hope it helps you.
