88. This is adiagram of a hylogenetic treee showing different animal phylum. As we can see in the figure the most ancient ancestor diveregd into two group. One og these growu develop into sponges with No tissues. The other offspring further evolved into a group of animal phylum all having true tissues.
The answer is C.
