D- Fertilisation is internal and development is through many larval stages. E- Some members like Planaria possess high regeneration capacity.

Step-by-step solution

A,D, and E are correct They have a dorso-ventrally flattened body. Flatworms are bilaterally symmetrical, triploblastic and acoelomate animals with organ level of organization. Specialised cells called flame cells help in osmoregulation and excretion. Fertilization is internal and development is through many larval stages. Some members like Planaria possess high regeneration capacity.
