Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Hemichordates possess a characteristic anterior extension of the digestive tract known as buccal diverticulum.
Step 1: Identify the phylum. Examples: \[ \textit{Balanoglossus},\quad \textit{Saccoglossus} \] These belong to Hemichordata.
Step 2: Special structure. The buccal diverticulum projects into the proboscis region. Hence, \[ \boxed{\text{Buccal diverticulum } \rightarrow \text{ Hemichordata}} \] Option (A) is correct.
