Mass number = protons +neutrons.
Atomic number = protons only
We can say that mass number = atomic number + number of neutrons.
The number of neutrons is what differentiates the isotopes of an element.
For hydrogen element, it has three isotopes namely; protium, deuterium and tritium which have 0,1 and 2 neutrons respectively. Thus the answer is C
