Statement-I: ${}^{12}\mathrm{C}$ has atomic mass of exactly 12 atomic mass unit (amu).

Statement-II: One amu is defined as a mass exactly equal to 1/12 of the mass of one carbon-12 atom.

Select the correct option:

Most stable isotope is ${}^{12}\mathrm{C}$ and atomic mass unit (amu) is equal to $\frac{1}{12}\mathrm{th}$ mass of one C-12 atom.

According to the standard definition, the value of atomic mass unit of mass is accurate value of $${\displaystyle \frac{1}{12}}$$of the mass of a carbon-12 atom.

Both statements are correct.
