Answer:
Step-by-step explanation:
Option B. Tree sap flows over the insect and hardens is the correct answer.
The preservation of an entire insect in tree sap that flows over the insect and hardens is a process known as amber fossilization. This process is a type of fossilization that can result in the remarkable preservation of insects or other small organisms trapped in the resin of ancient trees. Over time, the resin hardens into amber, preserving the enclosed insect in incredible detail, including its soft and hard tissues. This is a well-known method of fossilization that has provided valuable insights into the ancient life of insects and other small creatures.
