• B. Gliding and climbing
• C. Walking, floating and swimming
• D. All of the above

Answer 1

Answer: (D)

All of the above

Hydra makes varied movements with the tentacles while it sometimes remains attached to some surface in water. This movement may be in response to various stimuli. Looping is similar to crawling and is the most common type of locomotion. Somersaulting similar to looping is the normal method of locomotion. Gliding, climbing, floating, swimming and walking are all done with the tentacles.

So, the correct answer is 'All of the above'.
