Surely it is #""^14C#?

Explanation:

YOu have not given us a list of istopes, but the isotopic distribution of carbon is given [here..........](https://en.wikipedia.org/wiki/Isotopes_of_carbon)

#""^12C# is about 98.9% abundant.........#""^13C# is approx. 1.1% abundant. This nucleus allows solution (and now solid-state) spectroscopy, and direct characterization of organic compounds...

There are trace quantities of the heavier isotope, #""^14C#....

How many neutrons does each isotope contain?
