B. Coleorhiza
C. Mesocotyl
D. Scutellum

Answer

**Step-by-Step Solution:**

1. **Identify the Structure**: In maize (Zea mays), the structure that covers the plumule is known as the choleoptile.

2. **Understand the Function**: The choleoptile is a tubular sheath that serves as a protective covering for the plumule, which is the embryonic shoot of the plant.

3. **Describe the Characteristics**: The choleoptile is conical in shape and is capable of growth. It plays a crucial role in protecting the growing shoot tip as it emerges from the soil.

4. **Relate to Plant Development**: As the maize seed germinates, the choleoptile helps guide the plumule upwards towards the light, facilitating the plant's early development.

5. **Conclusion**: Therefore, in maize, the tubular sheath that covers the plumule is called the choleoptile.
