Solution

The correct options are
A
Potassium

B
Sodium

C
Aluminum

The elements that are at the top in the activity series are highly reactive and hence can displace any metals from their salts placed below them in the reactivity series. Here sodium, potassium and calcium are placed above iron in the activity series.

Lead is below iron in the reactivity series, so it cannot displace iron from its salt.
