The correct statement is:

Carbon dating is used for absolute dating, but index fossils are not.

Carbon dating (radiocarbon dating) provides an absolute age for organic materials by measuring the decay of carbon-14. In contrast, index fossils are used for relative dating; they help to identify the age of rock layers based on the presence of specific fossils known to have existed during certain time periods.
