Show answer & explanation
Correct answer: B
Explanation
Solution: The correct answer is Theaflavins.
Explanation:
☛ Theaflavins are polyphenol compounds that act as potent antioxidants found primarily in black tea.
☛ They are formed during the enzymatic oxidation (fermentation) of catechins when tea leaves are processed into black tea.
☛ Theaflavins are responsible for the characteristic reddish-orange color and unique brisk taste of black tea.
☛ As antioxidants, they help neutralize harmful free radicals and reduce oxidative stress in the human body.
