Solution

The elements that are able to donate or lose electrons present in its valence shell are metals.
Based on their ability to lose electrons metals are arranged in the decreasing order of their reactivity and are called the reactivity series.
The metals that is having a greater tendency to lose electrons are placed at the top that is they are very reactive.
In the reactivity series, the order is $K > N a (S o d i u m) > C a (C a l c i u m) > M g (M a g n e s i u m) > A l (A l u m i n i u m) > Z n (Z i n c) > F e > P b > H (H y d r o g e n) > C u (C o p p e r) > H g (M e r c u r y) > A g > A u (G o l d)$
More reactive metals are extracted by electrolysis, moderately reactive metals are extracted by reduction with carbon, and less reactive metals are extracted by various chemical reactions.
So Potassium $(K)$ : Reactive metal and extracted by electrolysis.
Iron $(F e)$ and Lead $(P b)$ : Medium reactivity and extracted by reduction with carbon
Silver $(A g)$ : Less reactivity and extracted by chemical reactions.
