D. indicated the significance of 'humors'.

Answer

To solve the question regarding the demonstration of normal body temperature in a person with black bile, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Black Bile**:
- Black bile is one of the four humours in ancient medical theories, which also include blood, phlegm, and yellow bile. It was believed to be associated with a melancholic temperament.

2. **Connection to Body Temperature**:
- The question implies that the presence of black bile in a person is linked to their body temperature. In historical contexts, body temperature was often thought to reflect one's health and temperament.

3. **Good Humour Hypothesis**:
- The good humour hypothesis suggests that the balance of these humours (including black bile) affects a person's health and mood. A person with an excess of black bile was thought to have a "cold" or "melancholic" personality.

4. **William Harvey's Contribution**:
- William Harvey is known for his discovery of blood circulation. His work disapproved the simplistic connections made by the good humour hypothesis, showing that body temperature and health are not solely determined by the humours.

5. **Conclusion**:
- The demonstration of normal body temperature in a person with black bile disapproves the good humour hypothesis. It indicates that health cannot be solely explained by the balance of humours, as demonstrated by Harvey's findings.

### Final Answer:
The correct answer is that the demonstration of normal body temperature in a person with black bile **disapproves the good humour hypothesis of health**.
