D) choanoflagellata
E) microsporidia

Question

Choanoflagellates are considered the possible "missing link" in the evolution from microbial eukaryotes to multicellular animals due to the presence of shared genes involved in cell signaling and adhesion, as well as their morphological similarity to the choanocyte cells found in sponges. Slime molds also have some characteristics of multicellularity and are sometimes considered a possible candidate for the missing link, but they do not share as many genes with animals as choanoflagellates do. Metazoa, eumycota, and microsporidia are all multicellular organisms that have evolved independently from different lineages, so they are not considered missing links.
