C. Exophthalmic goitre
D. Both (b) and (c)

Explanation

**Step-by-Step Solution:**

1. **Understanding Thyroxine Hormone**: Thyroxine is a hormone produced by the thyroid gland that plays a crucial role in regulating metabolism, growth, and development in the body.

2. **Identifying Hypersecretion**: Hypersecretion refers to the excessive production of a hormone. In this case, we are focusing on the hypersecretion of thyroxine.

3. **Recognizing Related Diseases**: We need to identify diseases associated with the hypersecretion of thyroxine. The two main conditions related to this are:
- Hyperthyroidism
- Exophthalmic goiter (also known as Graves' disease)

4. **Evaluating Options**:
- **Creatinism**: This condition is not related to thyroxine; it is caused by iodine deficiency and affects physical and mental development.
- **Hyperthyroidism**: This condition is characterized by the overproduction of thyroxine, making it a correct answer.
- **Exophthalmic Goiter**: This condition is also due to the overproduction of thyroxine, making it another correct answer.
- **BNC**: This option is not relevant as it does not specify a disease.

5. **Conclusion**: The diseases caused by the hypersecretion of thyroxine hormone are Hyperthyroidism and Exophthalmic Goiter.

**Final Answer**: The disease caused by the hypersecretion of thyroxine hormone is Hyperthyroidism (and Exophthalmic Goiter).
