Correct Option: B
In the electrochemical series, also known as the reactivity series, Hydrogen is placed at the top.
The electrochemical series is a list of elements in the order of their standard electrode potentials (or redox potentials).
Elements at the top of the series have a greater tendency to gain electrons and form negative ions, while elements below hydrogen tend to lose electrons and form positive ions.
