A.
how long the organism was alive.
B.
the relative age of the rock where it was found.
C.
the type of climate from which it came.
D.
how it became extinct.

Answer 1

B. the relative age of the rock where it was found.

Reason: fossils (especially index fossils) are used in relative dating—by knowing a fossil's relative age you can correlate and date the rock layers containing it using the principle of faunal succession.
