2. **Identifying the Innominate Bone:**
- In the context of the skeletal system, the innominate bone, also known as the hip bone, is formed by the fusion of three bones: the ilium, ischium, and pubis. This fusion occurs during the adult phase of development.

- **Option C: A vein** - This option is incorrect as well; innominate does not refer to a vein.
- **Option D: A part of skeleton and an artery** - This option is correct as it acknowledges that innominate refers to both the innominate bone (part of the skeleton) and the innominate artery.

4. **Conclusion:**
- Based on the analysis of the options, the correct answer is **Option D: a part of skeleton and an artery**.
