Answer:
Correct Answer: C
Solution:
Balanoglossus belong to class enteropneusta.
In certain cases, the proboscis pore does not communicate with the proboscis coelom, but terminate blindly, and may send off a narrow tubular diverticulum which opens into the neurocoel.
The proboscis sits in the collar somewhat like an acorn in its cup, a character that has given the name ?acorn worm? to the group.
