Explanation:

Carbon has an atomic number of 6 (number of protons). The most common isotope of carbon is carbon - 12. The mass number (sum of protons and neutrons) of carbon - 12 is 12. Using the formula \( \text{Number of neutrons}=\text{Mass number}-\text{Atomic number} \), we get \( 12 - 6=6 \).

Answer:

A. Six
