Answer: A. isotopes

Answer: (a) isotopes

Isotopes have the same atomic number \(Z\) (same number of protons) but different mass numbers \(A\) because the number of neutrons differs, e.g. \(^{1}_{1}\mathrm{H}\), \(^{2}_{1}\mathrm{H}\), \(^{3}_{1}\mathrm{H}\). Isobars have the same \(A\); isotones have the same number of neutrons.
