D Correct answer
Explanation

Antioxidants are molecules that neutralize harmful free radicals (unstable molecules that can damage cells), thereby reducing oxidative damage - which is 'damage caused by oxygen' in the form of reactive oxygen species. They are primarily obtained from plant-based foods rich in vitamins C, E, and A, plus minerals like selenium. By reducing oxidative stress, they help support immune function. All three statements accurately describe aspects of what antioxidants are and do.
