Why was carbon-12 chosen for the atomic mass unit?

WebAn isotope is a group whose constituents belong to the same chemical element but have different mass numbers. Carbon has two isotopes: 12C and 13C. Both show the same chemical features because of the same atomic number. But the mass of 13C is larger than that of 12C, because 13C has one more neutron.

"The dalton or unified atomic mass unit (symbols: Da or u) is a non-SI unit of mass widely used in physics and chemistry. It is defined as 1⁄12 of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest. The atomic mass constant, denoted mu, is defined identically, giving mu = m( C)/12 = 1 Da. This unit is commonly used in physics and chemistry to express the mass of atomic-scale objects… " - Mass of 12c atom
