Correct Answer - B
There are several records of very old yet viable seeds. The oldest one is of a lupine (Lupinus arcticus), excavated from Arctic Tundra. Seeds of Lupinus arcticus, alteast 10,000 years old were found in lemming burrows deeply buried in permanently frozen slit of Pleistocene ae in unglaciated central Yuzon. They readily germinated in the laboratory and have since grown into normal healthy plants.
