scientists can find the absolute age of a rock by using
a uranium 235 dating
b carbon 14 dating
c carbon 12 dating
d relative dating

Explanation:

Carbon-14 is normally used to date living organisms (all living things we know today contain mostly carbon).   It can be used for samples up to about 60000 years old.  Carbon-12 is the non-radioactive form that we encounter daily.  Relative dating determines dates relative to each other, such as ordering of period or events.

Uranium 235 dating can determine date samples a million years old and up, so is more suited for rocks.
