Figure 27.2
-Refer to the figure above and consider the following data: Brown algae protists) include unicellular and multicellular organisms. Red algae protists) include unicellular and multicellular organisms. Amoebae protists) include unicellular and multicellular organisms. Which of the following conclusions is consistent with the data presented?

A) Multicellularity evolved once; thus, animals are derived from the most recently evolved protists.
B) Multicellularity is a synapomorphy that defines a eukaryote.
C) Multicellularity evolved multiple times as eukaryotes diversified.
D) Multicellularity is more adaptive than unicellularity.
E) None of the above answers apply.
