What can be concluded about the carbon atom from 12C?
It has 6 neutrons and 6 protons.
The isotope symbol AX shows the mass number A on the top-left. For 12C, the atomic number of carbon is 6, so it has 6 protons. Mass number is protons plus neutrons, giving 12 minus 6 = 6 neutrons. A neutral atom has electrons equal to protons, so it has 6 electrons too. Hence the correct description is 6 neutrons and 6 protons.
