• B. Earthworm
• C. Hydra
• D. Liver Fluke

Answer 1

The correct option is C Hydra

Hydra has a cylindrical and tubular body. It belongs to the phylum Coelenterata (Cnidaria). Coelenterates are radially symmetrical and diploblastic animals. The organisms of this group have long tube-like tentacles. These tentacles are attached near the mouth region. These tentacles radiate outward in all directions. The organism can be divided into half and mirror images are formed when the organism is divided in any plane. The body wall is made up of two germ layers - ectoderm and endoderm.

Thus, the correct answer is option C.
