Question

Quizplus · Accepted Answer

The free-radical theory of aging proposes that the accumulation of free radicals, which are molecules with unpaired electrons that can damage cells, contributes to the aging process. Antioxidants counteract this damage by neutralizing free radicals and preventing them from causing further harm. Therefore, option B is the best choice because it describes the action of antioxidants as counteracting the cell damage caused by free radicals. The other options are not related to the free-radical theory of aging or the action of antioxidants.
