The correct answer is option 3: Deuterium oxide.

To understand why, let`s break down the options:

Option 1: Hydrogen oxide. This is not the chemical name for heavy water. "Hydrogen oxide" is a term that could refer to regular water (H2O) or other compounds containing hydrogen and oxygen.

Option 2: Deuterium dioxide. While "deuterium" is the heavy isotope of hydrogen, the chemical formula for heavy water is not "dioxide". The formula for heavy water is actually D2O (where D represents a deuterium atom).

Option 3: Deuterium oxide. This is the correct chemical name for heavy water. "Deuterium" refers to the heavy isotope of hydrogen, and "oxide" refers to a compound containing oxygen. The formula D2O indicates that heavy water consists of two deuterium atoms bonded to one oxygen atom.

Option 4: Heavy hydrogen oxide. This option is incorrect because it combines the terms "heavy hydrogen" and "oxide", rather than "deuterium" and "oxide".

In summary, the correct chemical name for heavy water is deuterium oxide, represented by the formula D2O.
