• B. Radially symmetrical and diploblasic
• C. Bilaterally symmetrical and triploblastic
• D. Biradially symmetrical and diploblastic

Answer 1

The correct option is B Radially symmetrical and diploblasic

• Cnidaria is a phylum containing over 10,000 species.
• They have two basic body forms: swimming medusa and sessile polyps, both of which are radially symmetrical with a mouth surrounded by tentacles that bear cnidocytes.
• Cnidarians are diploblastic, meaning they have two germ layers.

Thus, the correct answer is option B.
