b. Used as guides in relative dating

Explanation:

Index fossils are defined as the fossils of animal or plant that preserved in the rocks of the Earth. They are found mostly in marine system and are abundant in nature but for a limited time.

Index fossils are used as guides in relative dating as index fossils are found in rocks so it is easy to correlate the relative ages of rocks from different regions. Index fossils are widely used as correlation of strata as it founds the age of rocks and relation between different rocks.
