What three things give rise to all tissues and organs in animals?

a. the production of carbon dioxide through the process of photosynthesis

c should be the answer

fumikage isn't really a bird, and tsuyu does have teeth. tsuyu has a transformation quirk which still allows her to be partially human. otherwise we'd have a large frog running around. fumikage has teeth because again, he isn't a bird. his head was a quirk mixture if i'm correct.
