The correct statement is:
C. Carbon dating is used for absolute dating, but index fossils are not.
Carbon dating (radiocarbon dating) provides an estimated absolute age of organic materials up to about 50,000 years old, while index fossils are used to establish the relative ages of rock layers and the organisms within them, helping to correlate the ages of strata but not providing absolute ages.
