Answer

To solve the question, "Select the incorrect match," we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Adrenal Cortex - Glucocorticoid**:
- The adrenal cortex is indeed responsible for producing glucocorticoids, which are hormones that help regulate metabolism and immune response. The primary glucocorticoid produced is cortisol.
- **Conclusion**: This match is correct.

2. **Parathyroid Glands - Four in Number**:
- The parathyroid glands are typically four small glands located on the back of the thyroid gland. They play a crucial role in regulating calcium levels in the blood.
- **Conclusion**: This match is also correct.

3. **Hypothyroidism - Cretinism**:
- Cretinism is a condition that arises due to a deficiency of thyroid hormones (T3 and T4), leading to stunted physical and mental growth. This is indeed associated with hypothyroidism.
- **Conclusion**: This match is correct.

4. **Thymus - Steroid Hormone**:
- The thymus gland produces thymosin, which is involved in the development of T-cells (a type of white blood cell). However, thymosin is a peptide hormone, not a steroid hormone.
- **Conclusion**: This match is incorrect.

### Final Answer:
The incorrect match is **Thymus - Steroid Hormone**.
