The correct option is B Echinodermata
Evisceration is a method of autotomy involving the ejection of internal organs used by animals as a defensive strategy. The sea cucumber, phylum Echinodermata, possess this property of self-evisceration. When a sea-cucumber is attacked, it may expel some of its internal organs. This could either satisfy a predator or scare it off. The cucumber will then proceed to grow another set of organs (regeneration)
So, the correct answer is option B.
