The right option is; B. the ratio of carbon-14 to carbon-12 in a sample

Radiocarbon dating is a method that is used to determine the objective age of organic materials. This method uses the properties of radiocarbon. The amount of the radioactive isotope carbon-14 and the stable form of carbon (carbon-12) that is present in the sample is measured and the ratio of the carbon-14 to carbon-12 are compared against an internationally used reference standard
