Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. Tritium Oxide
  2. Hydrogen Peroxide
  3. Deuterium Oxide
  4. Distilled Water

Correct answer and explanation

Correct answer: Deuterium Oxide

Explanation: āœ… Correct Answer: C) Deuterium Oxide šŸ“š Explanation: Heavy water (Dā‚‚O) is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium. Deuterium has one proton and one neutron, making it twice as heavy as ordinary hydrogen. In nuclear reactors, it is used to slow down fast-moving neutrons so they can effectively trigger a nuclear fission chain reaction.
