Correct option: A.
${C^{12}}$
a
The atomic mass refers to the actual physical mass of an atom.
The atomic mass refers to the actual physical mass of an atom.
The atomic mass is very small in the numerical values that's why it is calculated on the basis of comparison with the mass of carbon-$12$ isotope.
