Answer

To determine which gymnosperm has an unbranched stem, we can analyze the options provided:

1. **Understanding Gymnosperms**: Gymnosperms are a group of seed-producing plants that do not form flowers or fruits. Their seeds are often exposed or borne on cones.

2. **Evaluating the Options**:
- **Pinus**: This is a genus of coniferous trees known for having branched stems.
- **Cycus**: This is a genus of cycads, which are known for their unbranched stems.
- **Cedrus**: This refers to cedar trees, which typically have branched stems.
- **Lycopodium**: This is not a gymnosperm; it is a genus of clubmosses, which are pteridophytes.

3. **Identifying the Correct Answer**:
- Among the options, Cycus is the only one known for having an unbranched stem. It typically has a stout, unbranched trunk and can bear multiple leaves at the top.

Thus, the correct answer to the question "Unbranched stem is a character of which gymnosperm?" is **Cycus**.
