Question

Chordates share these features with echinoderms:
I. Protostomeate condition
II. Radial and indeterminate cleavages
III. Schizocoelic coelom
IV. Enterocoelic coelom
V. Deuterostomeate condition

• A. I, II, III
• B. III, IV, V
• C. I, III, IV
• D. II, IV, V

Hint:

Deuterostomes = echinoderms & chordates. Protostomes = arthropods, annelids, mollusks. Cleavage type and coelom formation help distinguish.

Answer 1

The Correct Option is D

Chordates and echinoderms are deuterostomes (V). They exhibit radial and indeterminate cleavage (II) and have enterocoelic coelom formation (IV). Protostome characteristics (I, III) do not apply.
