Answer

To answer the question about which hormone lowers the blood sugar level in the body, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Hormones Listed**: The question provides a list of hormones: Insulin, Glucagon, Oxytocin, and Thyroxin.

2. **Understand the Functions of Each Hormone**:
- **Insulin**: This hormone is produced by the pancreas and is known to lower blood sugar levels by facilitating the uptake of glucose into the cells.
- **Glucagon**: Also produced by the pancreas, this hormone has the opposite effect of insulin; it raises blood sugar levels by promoting the release of glucose stored in the liver.
- **Oxytocin**: This hormone is produced by the pituitary gland and is primarily involved in childbirth and lactation. It does not have a direct role in regulating blood sugar levels.
- **Thyroxine**: This hormone is produced by the thyroid gland and is involved in regulating metabolism but does not directly lower blood sugar levels.

3. **Determine the Correct Answer**: Based on the functions of the hormones, Insulin is the hormone that lowers blood sugar levels in the body.

4. **Conclusion**: Therefore, the correct answer to the question is **Insulin**.
