Final Answer :
A
Explanation :
Atomic mass is equal to the sum of the neutrons and protons in the nucleus of an atom. It does not include the electrons, which have a negligible mass compared to the protons and neutrons. Isotopes may have different numbers of neutrons, but the atomic mass listed on the periodic table represents the weighted average of all the isotopes of an element.
