A Correct answer
Explanation

Heavy water is water where the hydrogen atoms are replaced by deuterium, a heavier isotope of hydrogen with one neutron. The chemical formula is D2O or deuterium oxide (²H₂O). Tritium oxide would be even heavier, while hydrogen peroxide (H₂O₂) is a different compound entirely.
