This is the remains, impressions, or other evidence of a former existence of life preserved in a rock

• A. Trace
• B. Mold
• C. Artifact
• D. Fossil

Answer: (D)

Fossils are preserved remains or signs of organisms from the past found in rock. This term covers actual hard parts like bones or shells, as well as impressions left when sediment hardens around an organism, and even traces of activity such as footprints or burrows. A mold is a specific type of fossil that is an impression of the organism, so it’s a narrower example of fossil preservation rather than the broad concept. An artifact is a human-made object, not evidence of ancient life. So the description given—remains, impressions, or other evidence of a former existence of life preserved in a rock—best fits fossil.
