oxidation
reduction

Explanation:

Question 12

In redox chemistry, an oxidizing agent gets reduced (causes oxidation in another substance), and a reducing agent gets oxidized (causes reduction in another substance). The question states the agent oxidizes (loses electrons) and causes reduction in another. So it's a reducing agent.

Reduction is defined as the process where an atom or ion's oxidation state decreases (gains electrons). Oxidation is the opposite (increase in oxidation state). Conservation relates to mass/charge conservation, and equation is a chemical formula representation. So the process with a decrease in oxidation state is reduction.

Answer:

B. reducing
