D. unpredictable

Answer

To solve the question regarding the effect of snake poison lowering blood pressure (BP) on the Basal Metabolic Rate (BMR) of a healthy person, we can follow these steps:

### Step-by-Step Solution:

1. **Understand BMR**:
- BMR stands for Basal Metabolic Rate, which is the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state (meaning that the digestive system is inactive, which requires about 12 hours of fasting in humans).
- It is essentially the rate at which the body uses energy to maintain basic physiological functions such as breathing, circulation, and cell production.

2. **Role of Thyroxine**:
- Thyroxine is a hormone produced by the thyroid gland that plays a significant role in regulating BMR.
- Higher levels of thyroxine typically lead to an increase in BMR, which in turn can elevate blood pressure and heart rate.

3. **Effect of Lowering Blood Pressure**:
- If snake poison is causing a decrease in blood pressure, it indicates that the metabolic processes are being affected negatively.
- A decrease in blood pressure suggests that the body is not maintaining its normal metabolic functions efficiently.

4. **Conclusion on BMR**:
- Since BMR is linked to the body's metabolic activity and energy production, a decrease in blood pressure due to the effects of snake poison would likely lead to a decrease in BMR.
- Therefore, if blood pressure is lowered, the BMR will also decrease.

5. **Final Answer**:
- The condition of the BMR will decrease if a snake poison is found to be lowering the blood pressure of a healthy person.
