Answer 1

Answer:

option d. (i) and (ii) only

Explanation:

Metals displace other metals that less reactive than the metal itself.

For example magnesium when placed in copper sulphate solution will displace copper because magnesium is more reactive.

Then calcium being more reactive than magnesium, it'll displace magnesium from the solution.

In 3rd and 4th senario, no reaction will take place.

(To know which metals are reactive and which are not, we need to remember the reactivity series of metals.)
