Final Answer:
In Bill Nye's story time, he mentions that long ago pine tree sap hardened into a gold-colored substance we call Amber.
Thus correct option is A) Amber
Step-by-step explanation:
Amber forms from ancient pine tree sap undergoing chemical changes over millions of years. The resin solidifies, encapsulating debris and evolving into durable, golden-hued amber. This process preserves ancient life, offering insights into bygone ecosystems. Amber's transformation reveals nature's enduring mysteries and the wealth of knowledge within this radiant relic.
