Answer 1

The correct statement is:

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

Carbon dating (or radiocarbon dating) provides an estimate of the age of organic materials in years (absolute dating), while index fossils are used to identify and correlate the relative ages of rock layers based on the presence of specific fossils that are known to have existed during particular time periods.
