it loses protons.

it gains protons.

it gains electrons.

it loses electrons.

The correct answer is: It loses electrons.

Explanation:

In the reactions of oxide reduction (redox), one substance gives up electrons and the other accepts them. Involved: reducing agent (yields electrons, increases its oxidation number: oxidizes) and an oxidizing agent (accepts electrons, decreases its oxidation number: reduces).
