A. Cotyledon
B. Endosperm
C. Tegmen
D. Testa

Answer

To answer the question about the scutellum of maize/caryopsis, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure**: The scutellum is a part of the seed structure in maize (Zea mays), which is a type of caryopsis (a dry fruit where the seed is fused with the fruit wall).

2. **Identifying the Seed Type**: Maize is classified as an endospermic seed. In endospermic seeds, the endosperm serves as the primary storage tissue for nutrients.

3. **Defining the Scutellum**: The scutellum is a specialized structure that acts as a cotyledon in maize. It is a shield-shaped, thin layer that is closely pressed against the endosperm.

4. **Function of the Scutellum**: The main function of the scutellum is to facilitate the transfer of nutrients from the endosperm to the developing embryo during germination and seedling growth.

5. **Evaluating the Options**: The options given are:
- A) Cotyledon
- B) Endosperm
- C) Tegmen
- D) Testa

Among these, the correct identification of the scutellum is that it is a reduced cotyledon.

6. **Conclusion**: Therefore, the scutellum of maize/caryopsis is best described as a cotyledon.

### Final Answer:
The scutellum of maize/caryopsis is a **cotyledon**.
