Question
Which of the following animal Phyla is characterized by the absence of body segmentation?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Cnidarians (e.g., jellyfish, sea anemones) exhibit radial symmetry and generally lack the true body segmentation seen in more complex phyla. Arthropoda, Annelida, and Chordata all display segmentation.
Hint
Consider the body plans of simpler, radially symmetric animals compared to those with bilateral symmetry and more complex organization.
