2. **Identifying the Options**: The options provided are:
- Acromegaly
- Gigantism
- Simmons disease
- Cushing's disease

3. **Analyzing Each Condition**:
- **Acromegaly**: This is a disorder caused by the hypersecretion of growth hormone in adults. It leads to the enlargement of bones and soft tissues, particularly noticeable in the jaw, forehead, and nose.
- **Gigantism**: This condition occurs in children due to excessive growth hormone before the growth plates close, leading to overall increased height and size, but it does not specifically mention lower jaw enlargement.
- **Simmons disease**: This is not a commonly recognized term in relation to jaw enlargement and is often confused with other conditions.
- **Cushing's disease**: This is caused by excess cortisol and does not typically result in jaw enlargement.

4. **Conclusion**: Based on the analysis, acromegaly is the condition that specifically causes the enlargement of the lower jaw due to the hypersecretion of growth hormone from the anterior pituitary gland after physical development is complete.

5. **Final Answer**: Enlargement of the lower jaw occurs in acromegaly.
