The active vitamin D hormone, known as calcitriol, primarily plays a crucial role in the absorption of calcium in the intestines. It enhances the intestinal absorption of calcium, which is vital for maintaining healthy bones and various bodily functions. While vitamin D also has a role in the absorption of phosphate, its most significant impact is on calcium absorption.

Among the options provided:

1. **Iron** - Vitamin D does not significantly influence the absorption of iron.
2. **Zinc** - Similar to iron, vitamin D does not directly improve zinc absorption.
3. **Copper** - There is no strong link between vitamin D and copper absorption.
4. **Calcium** - Vitamin D is essential for increasing calcium absorption in the gut.

### Final Answer
**Calcium**
