The example of dicot endospermic seed is ….

Options

A. castor
B. pea
C. mango
D. bean

Answer

To determine the example of a dicot endospermic seed, we need to understand the characteristics of endospermic seeds and identify which of the given options fits this description.

### Step-by-Step Solution:

1. **Understand Endospermic Seeds**: Endospermic seeds are those seeds that retain the endosperm at maturity. The endosperm serves as a nutrient source for the developing embryo.

2. **Identify the Options**: The question provides several options, including Castor, Pea, Mango, and Beans. We need to analyze each option to see if they are endospermic or non-endospermic.

3. **Analyze Each Option**:
- **Castor**: In castor seeds, the endosperm remains after maturation and provides nutrition to the embryo. Thus, castor seeds are classified as endospermic.
- **Pea**: In pea seeds, the endosperm is fully utilized by the developing embryo, leaving no endosperm at maturity. Therefore, pea seeds are non-endospermic.
- **Mango**: Similar to peas, mango seeds also absorb all the endosperm during development, making them non-endospermic.
- **Beans**: Like peas and mangoes, beans also utilize the endosperm completely, so they are non-endospermic as well.

4. **Conclusion**: After analyzing all the options, we find that only castor seeds retain the endosperm at maturity. Therefore, the correct answer is **Castor**.

### Final Answer:
The example of a dicot endospermic seed is **Castor**.
