Solution
The correct option is B Cycas
Cycas deserve the qualifying title of "living fossils," since this group of plants reached its highest point of evolution in the Mesozoic (about 200 million years ago) and, since then, has been declining, albeit without showing any appreciable changes in their evolution. Fossil Cycas from the the Paleozoic (about 240 million years ago) have many characteristics similar to the Cycas of the present time; thus, the name living fossils.
