The mass defect of a carbon-14 nucleus is (6mp + 8mn) – mc – 14.
To find the correct option among all the options, we need to know about the mass defect.
Mathematically, mass defect is given as
∆m = mass of all nucleons - mass of nucleus
= Mass of protons + mass of neutrons - mass of nucleus
Thus, we can conclude that the option (a) is correct.
