The correct answer is **C, the age of the rock**.
Index fossils are used by geologists to help determine the relative age of the rock layers in which they are found. These fossils are typically from species that were widespread but existed for a relatively short period, allowing geologists to correlate the ages of rock layers across different geographic locations.
