Solution

The process of oxidation involves the loss of electrons. In the given options, the reaction Zn → ZnO represents oxidation. Here's why:

  1. Zn is converted to ZnO. This means that Zn (Zinc) is combined with O (Oxygen) to form ZnO (Zinc Oxide).

  2. Oxygen is highly electronegative and it attracts the electrons towards itself. So, when Zn combines with O, it loses electrons to Oxygen.

  3. The loss of electrons is what characterizes oxidation. Therefore, Zn being oxidized to ZnO represents an oxidation process.
