Which of the following would most likely be the prototype for a flower?

Question

an aster
a magnolia
a hibiscus
a gladiola
a rose

I have no idea i know that a prototype serves as typical example but to me all the answers work

Answer 1

The ancestor to the magnolia is thought to be a probable prototype, but frankly, there is much incomplete evidence, and there are gaps. So "most likely" is the key. We just don't know for certain yet.
