B Correct answer
Explanation

An oxidizing agent gains electrons from another substance in a redox reaction. When hydrogen reacts with sodium (Na), it gains an electron to form H⁺ while Na loses an electron to form Na⁺. Thus hydrogen is reduced (acts as oxidizing agent) and sodium is oxidized. With more electronegative elements like Br₂, N₂, or O₃, hydrogen acts as a reducing agent (loses electrons).
