Which term describes a long, flexible limb used for grasping?

• A. Cephalopod
• B. Gastropod
• C. Bivalve
• D. Tentacle

Answer: (D)

A tentacle is a long, flexible limb designed to reach out and grasp objects or prey. In animals like cephalopods, tentacles extend to seize prey from a distance and often have suction cups or hooks to secure a grip, then bring the captured item toward the mouth. Arms (the other flexible limbs cephalopods have) are typically shorter and used for manipulation rather than the extended grasping action. The other terms describe whole groups of animals (cephalopod, gastropod, bivalve) rather than a specific grasping limb, so the word that best fits the description is tentacle.
