Both:

• A. have a complete digestive tract
• B. have a ventral solid nerve cord

Answer 1

The correct option is C are segmented

Annelids and arthropods have long been considered each other's closest relatives, as evidenced by similarities in their segmented body plans. The resulting tree suggests that the molluscs and annelids form a monophyletic lineage and unites the molluscan taxa to a monophyletic group. So, the correct option is 'are segmented'
