• A. Ancient remains
• B. Fossil
• C. Adaptation
• D. Evolution

Answer: (B)

Fossils are the preserved remains or traces of organisms that lived in the past. They can be actual remains like bones or shells, or traces such as footprints, burrows, or imprints that have been preserved in rocks, amber, ice, or other materials. This term specifically identifies evidence from ancient life, whether it’s a body fossil or a trace fossil. The other terms don’t fit because they describe processes or general ideas rather than preserved evidence: ancient remains is just a descriptive phrase, adaptation is a trait that helps survival, and evolution is the process of change over generations.
