Options

A. Mosses
B. Club mosses
C. Spike mosses
D. All the above

Answer

### Step-by-Step Solution:

1. **Understanding Bryophyta**: Bryophyta is a division of non-vascular plants that includes mosses, liverworts, and hornworts. They are characterized by their simple structure and lack of true roots, stems, and leaves.

2. **Identifying Mosses**: Mosses are small, non-vascular plants that typically form dense green mats in damp and shady environments. They are composed of simple leaves that are usually one cell thick.

3. **Characteristics of Mosses**:
- Mosses do not have seeds; they reproduce via spores.
- They may have poorly developed conducting tissues, which are different from those found in vascular plants.
- After fertilization, mosses develop sporophytes.

4. **Understanding Club Mosses**: Club mosses, also known as lycophytes, are flowerless and seedless plants that belong to the family Lycopodaceae. They are vascular plants and differ from true mosses in their structure and reproductive methods.

5. **Understanding Spike Mosses**: Spike mosses belong to the family Selaginellaceae and are also vascular plants. They are distinct from both mosses and club mosses.

6. **Conclusion**: Based on the definitions and characteristics discussed, Bryophyta primarily includes mosses. Therefore, the correct answer to the question "Bryophyta includes:" is "mosses."

### Final Answer:
Bryophyta includes: **Mosses.**
