D. Equisetum

Answer

To solve the question "An example of a vascular cryptogam is," we need to analyze the options provided: Ginkgo, Marchantia, Cedrus, and Equisetum.

### Step-by-Step Solution:

1. **Understanding Vascular Cryptogams**:
- Vascular cryptogams are plants that have vascular tissues (xylem and phloem) but do not produce seeds. They are typically classified under Pteridophytes (ferns and their relatives).

2. **Analyzing the Options**:
- **Ginkgo**:
- Ginkgo is a gymnosperm, which means it produces seeds. Therefore, it cannot be a vascular cryptogam.
- **Marchantia**:
- Marchantia is a bryophyte, which is a group of non-vascular plants. It lacks true vascular tissues and does not fit the definition of vascular cryptogams.
- **Cedrus**:
- Cedrus is also a gymnosperm and produces seeds. Thus, it is not a vascular cryptogam.
- **Equisetum**:
- Equisetum, commonly known as horsetail, is a member of the Pteridophytes. It has vascular tissues (xylem and phloem) and does not produce seeds, making it a vascular cryptogam.

3. **Conclusion**:
- The only option that fits the criteria of a vascular cryptogam is **Equisetum**.

### Final Answer:
- An example of a vascular cryptogam is **Equisetum**.
