Solution
The correct option is D Both A and B
Cycads were more common than they are now during the Triassic and Jurassic periods (about 245 to 140 million years ago), before the flowering plants appeared. This is why cycads are sometimes referred to as "living fossils", but the term could really be just as accurately applied to a pine tree (conifer).
