During archaeological excavations near the Dead Sea, seeds of Phoenix dactylifera, which is the species of palm tree that produces dates, were discovered. Some of these seeds were reported to be around 2000 years old and still viable, meaning they had the potential to germinate and grow into new plants.
This discovery was significant as it provided insights into the longevity and resilience of seeds, as well as the ancient agricultural practices in the region.
Therefore, the correct answer is (C) Phoenix dactylifera (date palm).
