Which dinosaur am I?

Just as you think you were safe you find yourself close to another dinosaur.  Except this one is a herbivore and is about 20 feet long.  It is a very protected dinosaur because it has plates, spikes, and a club-like tail to protect itself.  What dinosaur am I?


A. Euplocephalus

B. Spinosaurus

C.  Brontosaurus
