Correct Answer: Acoelomates
Solution : The correct option is acoelomates
An organism without a body cavity is referred to as an acoelomate. A fluid-filled space between the body wall and the digestive tract, which is prevalent in more complex creatures, is absent in acoelomate species. As a result, their organs are usually linked directly to the body wall. Acoelomate creatures include flatworms (Platyhelminthes).
