B. lower than
C. same as
D. incomparable to

Answer

To solve the question regarding the heart rate of a well-trained athlete compared to a normal person at rest, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks about the heart rate of a well-trained athlete at rest compared to that of a normal person.

2. **Define Heart Rate**: Heart rate is the number of times the heart beats in one minute, measured in beats per minute (BPM).

3. **Heart Rate in Athletes**: Well-trained athletes typically have a lower resting heart rate due to their cardiovascular fitness. This is a result of regular intense exercise, which strengthens the heart muscle.

4. **Mechanism of Lower Heart Rate**: The heart of an athlete is more efficient. With each contraction, a well-trained heart pumps a larger volume of blood compared to a normal heart. This means that fewer beats are needed to circulate the same amount of blood.

5. **Typical Heart Rates**:
- **Athlete's Heart Rate**: Approximately 40 BPM (beats per minute) at rest.
- **Normal Person's Heart Rate**: Typically ranges from 65 to 100 BPM at rest.

6. **Conclusion**: Since the resting heart rate of a well-trained athlete is significantly lower than that of a normal person, we conclude that the heart rate of an athlete at rest is lower than that of a normal person.

### Final Answer:
The heart rate of a well-trained athlete at rest is **lower** than that of a normal person.
