The correct option is D.

Mole is a measurement used in chemistry which allows us to measure out the same quantity of matter in different substances. Mole allows scientist to measure two substances, for instance, magnesium and sodium, which have equal amount of atoms. Thus, a mole of magnesium contains the same number of atoms as a mole of sodium.
