A
Lupinus arcticus
💡 Explanation:
There are several records of very old yet viable seeds. The oldest one is of a lupine(Lupnius arcticus) excavated from Arctic Tundra. Seeds of Lupinus arcticus, atleast $10,000$ years old were found in lemming burrows deeply buried in permanently frozen silt of Pleistocene age in ungladated central Yuzon. They readily germinated in the laboratory and have since grown into normal healthy plants.
