A

Metal Q will displace the cation of P from its aqueous solution and deposit the metal P

B

Both metals Q and R will displace the cation of P from its aqueous solution and deposit the metal P

C

Metal R will displace the cation of P from its aqueous solution and deposit the metal R

D

Metal P will displace the cation of R from its aqueous solution and deposit the metal R

Text Solution

Verified by Experts

The correct Answer is:
