Question
In which among the given minor phyla is the alimentary canal U shaped?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Both Bryozoa (moss animals) and Phoronida (horseshoe worms) possess a U-shaped alimentary canal. This feature allows the anus to be located near the mouth, which is an adaptation for their sessile, filter-feeding lifestyle. In Bryozoa, this is part of the lophophore complex, while in Phoronida, the U-shaped gut is a defining characteristic.
Hint
Think of which filter-feeding, sessile phyla have the anus positioned close to the mouth.
