You forget they didnt say kingdom animalia they said which of the following invertebrates as in things that dont have a back bone plus
Protozoa are the simplest and most primitive of all the invertebrates and they evolved first before the other invertebrate groups listed in the options.
So the correct answer is E (protozoa)

Though protozoa doesn't have a backbone, it is still not classified under invertebrates in kindom animalia.
Protozoans are under kingdom protista
So the answer is c because it is part of the earliest invertebrates
