-Refer to Figure 33.1.Suppose new molecular analyses indicated that the phylum Annelida had diverged from the arthropod lineage after Onychophora and Tardigrada.What would this imply about protostome evolution?

A) Segmentation evolved only once within protostomes.
B) The annelid lineage gained and then lost the ability to molt.
C) The annelid lineage gained and then lost jointed limbs.
D) Segmentation evolved only once within protostomes;the annelid lineage gained and then lost the ability to molt.
E) Segmentation evolved only once within protostomes;the annelid lineage gained and then lost jointed limbs.
