Nuclear endosperm is a character of :

Options

A. Coconut (copra)
B. Utricularia
C. Coconut (milk)
D. Asphodelus

Answer

To determine which option represents the character of nuclear endosperm, we can analyze the definitions and characteristics of nuclear endosperm and the given options.

### Step-by-Step Solution:

1. **Understand Nuclear Endosperm**: Nuclear endosperm is formed when the primary endosperm nucleus undergoes mitotic divisions without the formation of cell walls. This results in a liquid endosperm containing multiple nuclei, which is nutritious.

2. **Analyze the Options**:
- **A. Coconut or copra**: Coconut milk (or coconut water) is a liquid that contains nuclear endosperm, as it is formed without cell wall formation.
- **B. Utricularia**: This is a genus of carnivorous plants and does not typically produce nuclear endosperm.
- **C. Coconut**: This option is similar to A, as it refers to the same fruit that produces coconut milk.
- **D. Aspergillus**: This is a genus of fungi and does not produce nuclear endosperm.

3. **Identify the Correct Answer**: Both options A (Coconut or copra) and C (Coconut) refer to the coconut, which is known for its liquid endosperm (coconut milk). However, since the question asks for a character of nuclear endosperm, the best answer is **C. Coconut**.

4. **Conclusion**: The character of nuclear endosperm is primarily associated with coconut, particularly in its liquid form (coconut milk).

### Final Answer: C. Coconut
