Explanation:

- The relative atomic mass unit is defined as 1/12th of the mass of a carbon-12 atom. Therefore, the mass of one carbon-12 atom is 12 atomic mass units (amu).
- If we consider 1/6th of the mass of a carbon-12 atom as the relative atomic mass unit, then the mass of one carbon-12 atom would be 6 amu.
- This means that the atomic mass of any other element would also be expressed in terms of 1/6th of the mass of a carbon-12 atom.
- So, the atomic mass of an element, which is the mass of one mole of that element, would be half of the value obtained using the conventional atomic mass unit.
- Therefore, if we use 1/6th of the mass of a carbon-12 atom as the relative atomic mass unit, the mass of one mole of a substance would decrease twice.

Hence, option D is the correct answer.
