The correct answer is option (Q) and (R)

No reaction will take place in Test Tube Q and R in both the sets of experiment. It is because according to displacement reaction a more reactive metal displaces a less reactive metal in a solution. But in Test Tube Q and R, a less reactive metal is trying to displace a more reactive metal in a compound which cannot happen. Hence, No reaction will take place in Test Tube Q and R.

The more reactive metals can displace a less reactive metal in a solution or compound. But a less reactive metal can never displace a more reactive metal in any type of solution or compound.
