The correct option is A Both B and C
When an iron nail is placed in a blue-coloured copper sulphate solution, copper from copper sulphate gets displaced and gets deposited on the iron nail and the solution turns green.
Fe + $C u S O_{4} \to F e S O_{4} + C u$
This is an example of a displacement reaction.
