### Understanding Endothelins

Endothelins are a group of potent vasoconstrictors that are primarily produced by endothelial cells. They play a crucial role in various physiological processes, including regulating vascular tone and blood pressure.

### Analyzing the Options

1. **Nitric Oxide**: This is actually a vasodilator, not a vasoconstrictor.
2. **Vasodilator**: This is incorrect since endothelins are known to cause constriction of blood vessels.
3. **Inflammatory Marker**: While endothelins may be involved in inflammatory processes, they are primarily recognized for their vasoconstrictive properties.
4. **Vasoconstrictor**: This is the correct option, as endothelins cause blood vessels to constrict, which increases blood pressure.

### Final Answer

d. **vasoconstrictor**
