The animal found by the boy belongs to phylum mollusca. Mollusca is the second largest phylum after arthropoda and includes predominantly marine animals. They are triploblastic, bilaterally symmetrical, schizocoelic and unsegmented protostomes. They have moist skin, a complete digestive tract, a ventral nerve cord, and had gone through torsion.

The correct answer is option 'C', Mollusca.
Mollusca is a phylum of invertebrate animals that includes a diverse range of organisms such as snails, slugs, clams, octopuses, and squids. Let's analyze the characteristics mentioned in the question to understand why the animal belongs to this phylum.
1. Moist skin: Mollusks have a soft, moist skin that is covered by a thin layer of mucus. This moist skin helps in respiration and provides protection.
2. Complete digestive tract: Mollusks have a complete digestive tract, meaning they have a separate mouth and anus. This allows for efficient digestion and absorption of nutrients.
3. Ventral nerve cord: Mollusks have a ventral nerve cord running along the underside of their body. This nerve cord helps in coordination and control of body movements.
4. Torsion: Torsion refers to a twisting of the body during development. Mollusks undergo torsion, which results in the rotation of the visceral mass (containing the organs) by 180 degrees. This twisting is a unique characteristic of mollusks.
Based on these characteristics, it can be concluded that the strange animal the student brought home belongs to the phylum Mollusca.
Some additional characteristics of mollusks include:
- Most mollusks have a muscular foot that is used for locomotion.
- They usually have a hard external shell made of calcium carbonate, although not all mollusks have shells.
- Mollusks exhibit a wide range of feeding strategies, including herbivory, carnivory, and filter-feeding.
- They have a well-developed circulatory system, with a heart and blood vessels.
- Mollusks show a high degree of morphological diversity, with variations in body shape, size, and appendages.
Overall, the phylum Mollusca is a diverse group of animals with unique characteristics, and the animal described in the question fits the criteria for being a mollusk.
