• B. A-I B-II C-IV D-III
• C. A-III B-I C-II D-IV
• D. A-I B-III C-II D-V

Answer 1

The correct option is C A-III B-I C-II D-IV

Stomochord is a hollow tube-like structure. This flexible rod-like structure is found in the hemichordates like the Balanoglossus. This is present in the adults and extends from the pharynx to the proboscis.

The coelomic cavity of the Hirudinea is composed of a specialised type of tissue. This tissue is known as botryoidal tissues. These are tubular cells which contain blood-like fluid.

Captacula is the tentacles. These are present in the organisms in which there is no developed head. This is used as sensory organs. They are also helpful in digging and obtaining the food. This is present in the Dentalium.

Rhabdites are the rod-like structures. These are the structures which are present in the cells of the epidermis. This is the characteristic product which is secreted in Turbellaria. These are present in Dugesia.

Thus, the correct answer is option C.
