Solution
The correct option is B Metal A is more reactive than metal B. In a reaction between a metal and the salt solution of another metal, the more reactive metal can displace a less reactive metal from its compound in the solution. This is known as a displacement reaction.
In the given reaction, metal A displaces metal B from its salt solution. Thus, metal A is more reactive than metal B.
