The crucial difference between relative dating and absolute dating is that
a) relative dating requires relatives of the fossil to be living while absolute dating does not.
b) absolute dating always requires carbon-14 to be present in a sample while relative dating does not.
c) relative dating gives age compared to other nearby objects while absolute dating always gives a numerical age.
d) relative dating gives a numerical age that is relatively close while absolute dating gives age by comparing nearby fossils.

 C.

Explanation: Relative dating is the technique used to know which object or item is older in comparison to the other one. The absolute dating is the technique which tells about the exact age of the artifact or the site using the methods like carbon dating.
