The correct Answer is:
To determine which of the given organisms has a lily-like appearance, we can analyze each option provided. 1. **Brittle Star**: - The brittle star is a type of echinoderm that resembles a starfish. It has a central disk with long, slender arms that radiate outwards. While it is an interesting organism, it does not have a lily-like appearance. **Hint**: Consider the physical structure of the brittle star and how it compares to a starfish. 2. **Pentaceros**: - Pentaceros, also known as the sea pentagon, is characterized by its five arms that give it a pentagonal shape. This shape is distinct and does not resemble a lily plant. **Hint**: Think about the geometric shape of Pentaceros and how it differs from the structure of a lily. 3. **Antidone**: - Antidone is the scientific name for sea lily. Sea lilies have a stalk-like structure and a crown of feathery arms that resemble the petals of a lily flower. This resemblance to a lily plant is why it is called a sea lily. **Hint**: Visualize the structure of sea lilies and compare it to the appearance of a typical lily plant. Based on this analysis, the organism that has a lily-like appearance is **Antidone (sea lily)**. Therefore, the correct answer is option C. **Final Answer**: C. Antidone (sea lily) has a lily-like appearance. ---
