The correct response is:

**the ratio of carbon-12 to carbon-14**

This ratio is used in radiocarbon dating to determine the absolute age of organic materials. By measuring the relative amounts of carbon-12 and carbon-14 in a sample, scientists can estimate how long it has been since the organism died.
