The correct statement is:
**B. 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 isotopes. Index fossils, on the other hand, are used to identify and correlate the relative ages of rock layers but do not provide an absolute age.
