Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): The molecular evidences suggest that the sister group of sponges is not choanoflagellates, but mesomycetozoa, a group of parasitic protists. So, can this hypothesis be correct given that these parasites lack collar cells?
Reason (R): The collar cells of sponges bear a significant resemblance to a choanoflagellate cell suggesting that the last common ancestor of animals and their protist sister group might have resembled a choanoflagellate. In this regard, mesomycetozoans could still be sister group of animals. The lack of collar cells in mesomycetozoans would indicate that over the time, their structure evolved in a way that it no longer resembled a choanoflagellate cell pointing out to convergent evolution.
In the light of the above statements, choose the most appropriate answer from the options given below:
