D. Crinoidea

Explanation

**Step-by-Step Solution:**

1. **Identify the Organism**: The question asks about the classification of the starfish. First, we need to recognize that a starfish is not a true fish but rather a marine animal with a distinct shape.

2. **Determine the Phylum**: Starfish belong to the phylum Echinodermata. Echinoderms are characterized by their radial symmetry and a water vascular system. This phylum includes other marine animals like sea urchins and sea cucumbers.

3. **Classify the Starfish**: Within the phylum Echinodermata, starfish specifically belong to the class Asteroidea. This class includes various species of starfish, which are known for their star-like shape.

4. **Review Other Options**: The question may provide multiple-choice options. It is essential to differentiate Asteroidea from other classes:
- **Ophiuroidea**: This class includes brittle stars, which are different from starfish.
- **Holothuroidea**: This class includes sea cucumbers, which again are not starfish.
- **Crinoidea**: This class includes feather stars, which are also distinct from starfish.

5. **Select the Correct Answer**: After reviewing the options, the correct answer is **Asteroidea**, as it is the only class that includes starfish.

**Final Answer**: Starfish belongs to the class **Asteroidea**.
