Answer

Brief Explanations:

Index fossils are from organisms that were abundant, widespread, and lived for a relatively short - time period. An organism found in abundance nearby is more likely to meet the criteria of being abundant and widespread compared to the other options. Organisms still alive today are not fossils. A single - found fossil or one from an organism in a narrow area is not ideal for an index fossil.

Answer:

It is the remains of an organism that is found in abundance nearby.
