Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks which hormone is concerned with urine.

2. **Analyze the Options**: The options provided are:
- Option 1: Oxytocin
- Option 2: Vasopressin
- Option 3: Prolactin
- Option 4: Cortisol

3. **Evaluate Each Option**:
- **Option 1: Oxytocin**: This hormone is primarily involved in stimulating uterine contractions during childbirth and is not related to urine production or regulation. Therefore, this option is incorrect.

- **Option 2: Vasopressin**: Also known as antidiuretic hormone (ADH), vasopressin is crucial in regulating the body's water balance and plays a significant role in concentrating urine by promoting water reabsorption in the kidneys. This makes it the correct answer.

- **Option 3: Prolactin**: This hormone is mainly responsible for milk production in lactating females and does not have a direct role in urine regulation. Thus, this option is incorrect.

- **Option 4: Cortisol**: Cortisol is a steroid hormone that helps regulate metabolism and the immune response, and it increases glucose levels in the blood. It does not directly influence urine production, making this option incorrect as well.

4. **Conclusion**: After evaluating all the options, the hormone that is concerned with urine is **Vasopressin** (Option 2).

**Final Answer**: Vasopressin
