Metal A dipped in a salt of metal B displaces B from the solution. This shows that
(a) A is more reactive than B.
(b) B is more reactive than A.
(c) both A and B are equally reactive.
(d) no such conclusion can be drawn.

Solution

(a) A is more reactive than B
More reactive metal (A) can displace a less reactive metal (B) from its salt solutions. More reactive metals are placed above comparatively less reactive metals in the reactivity series and can displace metals below them in the reactivity series.
