Answer

To answer the question "Which of the following is not a non-endospermous seed (in matured condition)?", we need to understand the difference between endospermous and non-endospermous seeds.

### Step-by-Step Solution:

1. **Define Endospermous Seeds**:
- Endospermous seeds are those seeds in which the endosperm is present and not completely utilized by the time the seed matures. This means that the endosperm remains as a source of nutrition for the developing plant embryo.

2. **Define Non-Endospermous Seeds**:
- Non-endospermous seeds are those seeds in which the endosperm is completely utilized during the development of the seed. As a result, these seeds do not have any endosperm left at maturity.

3. **Identify Examples**:
- Common examples of endospermous seeds include coconut and beans. In these seeds, the endosperm is present and serves as a food reserve for the embryo.
- On the other hand, seeds like peas and maize are examples of non-endospermous seeds where the endosperm is completely consumed.

4. **Analyze the Options**:
- The question asks for the seed that is not non-endospermous, which means we are looking for an endospermous seed.
- From the examples discussed, coconut and beans are endospermous seeds.

5. **Conclusion**:
- Therefore, if the options provided include coconut and beans, one of these would be the correct answer to the question, as they represent seeds that are not non-endospermous.

### Final Answer:
- The seed that is not non-endospermous (i.e., is endospermous) is **coconut** or **bean** (depending on the options provided).
