### Answer to the Question

Among the options provided, the hormone responsible for vasodilation is:

**c. Atrial natriuretic peptide (ANP)**

### Explanation

Atrial natriuretic peptide is a hormone produced by the heart's atria. It promotes vasodilation, which helps to reduce blood pressure by relaxing the blood vessels. This is in contrast to other hormones listed:

1. **Angiotensin II** - primarily causes vasoconstriction.
2. **Antidiuretic hormone (ADH)** - primarily helps in water retention and can cause vasoconstriction in certain contexts.
3. **Norepinephrine** - primarily causes vasoconstriction and increases blood pressure.
4. **Vasopressin** - also known as ADH, induces water retention and can cause vasoconstriction.

Thus, the correct answer is Atrial natriuretic peptide, due to its role in promoting the widening of blood vessels.
