Answer

To solve the question, "An example of a seed with endosperm, perisperm, and caruncle is," we will analyze the definitions and characteristics of the terms involved, and then identify which of the given options fits all the criteria.

### Step-by-Step Solution:

1. **Understand the Structures:**
- **Endosperm:** This is a nutritive tissue that develops from the fertilization of one male gamete with two polar nuclei in the central cell of the ovule. It provides nourishment to the developing embryo and is typically triploid.
- **Perisperm:** This is the remnant of the nucellus (the tissue of the ovule) that persists after fertilization. It serves as an additional source of nutrition for the seed.
- **Caruncle:** This is an outgrowth that forms near the hilum (the scar on the seed where it was attached to the ovule) from the integument of the seed. It covers the hilum and micropyle and is characteristic of certain seeds.

2. **Analyze the Options:**
- **Lily:** Typically has an endosperm but does not have a perisperm or caruncle.
- **Castor:** Known to have endosperm, perisperm, and a caruncle. It is a dicot seed with two cotyledons and fits all the criteria.
- **Cotton:** Primarily has endosperm but lacks a perisperm and caruncle.
- **Coffee:** Contains endosperm but does not have a perisperm or caruncle.

3. **Conclusion:**
- Based on the definitions and analysis of the options, the only seed that contains endosperm, perisperm, and caruncle is **Castor**.

### Final Answer:
The example of a seed with endosperm, perisperm, and caruncle is **Castor**.
