Solution

The correct option is B
It does not compare the relative reactivity of metals.

The series in which elements are arranged in order of their reactivity is known as an electrochemical series. Above hydrogen the more reactive elements are placed and the least reactive metals are placed below it. In short, this series compares the relative reactivity of metals.
