C)The colonial flagellate hypothesis states that metazoans arose from choanoflagellate-like protists.

Most taxonomists actually agree that the origin of the metazoans is monophyletic, meaning that all animals are descended from a single common ancestor. The other statements are true: the multinucleate hypothesis, the colonial flagellate hypothesis, and the polyphyletic origin hypothesis are all hypotheses about the origin of metazoans, and molecular data does suggest a closer relationship between metazoans and flagellates than to ciliates.
