The standard reduction potentials at 298K for the following half-cell ...

In electrochemical series (ECS), elements have been arranged in the increasing standard reduction potential starting from most negative to most positive value w.r.t. SHE (E°_she= 0.00 V).

Most negative standard reduction potential means most easily oxidised and thus is the best reducing agent.

OR Reducing agent in (ECS) is always above oxidising agent. Thus, Zn(s) is the best reducing agent in given set.
