Options

A. Pea
B. Castor
C. Bean
D. Gram

Answer

To determine which seed is a dicot albuminous seed, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Seeds**:
- Seeds are the end products of fertilization in angiosperms. They contain an embryo, which develops into a new plant.

2. **Identify Types of Seeds**:
- Seeds can be categorized based on the presence of endosperm (the tissue that provides nutrients to the developing embryo).
- **Albuminous Seeds (Endospermic Seeds)**: These seeds retain some endosperm at maturity.
- **Exalbuminous Seeds (Non-Endospermic Seeds)**: These seeds have consumed the endosperm during embryo development.

3. **Focus on Dicot Seeds**:
- Dicot seeds can be either albuminous or exalbuminous.
- Albuminous dicot seeds retain endosperm, while exalbuminous seeds do not.

4. **Examples of Albuminous Seeds**:
- Common examples of dicot albuminous seeds include coconut and castor.
- These seeds have a significant amount of endosperm that remains at maturity.

5. **Examples of Exalbuminous Seeds**:
- Examples of exalbuminous seeds include pea, bean, and gram. These seeds do not have any endosperm left as it is utilized during the development of the embryo.

6. **Conclusion**:
- Based on the examples provided, the dicot albuminous seed from the options given is **castor**.

### Final Answer:
A dicot albuminous seed is **castor**.
