Answer

To determine what maize grain is, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of Maize Grain**:
- Maize grain is composed of several parts, including the endosperm, embryo, and seed coat.

2. **Identifying the Type of Seed**:
- Maize grain is classified as an albuminous seed, also known as an endospermic seed. This means it contains a significant amount of endosperm that serves as a food reserve.

3. **Defining Endosperm**:
- The endosperm is the tissue that provides nourishment to the developing embryo within the seed. It is rich in starch and other nutrients.

4. **Differentiating Between Seed Types**:
- There are two main types of seeds: albuminous (endospermic) seeds, which retain some endosperm, and non-albuminous (non-endospermic) seeds, where the endosperm is fully utilized to form cotyledons.

5. **Conclusion**:
- Since maize grain retains its endosperm and is primarily a seed that contains an embryo and food storage, we can conclude that maize grain is a seed.

### Final Answer:
- Therefore, the correct answer to the question "Maize grain is" is **Option B: Seed**.
