Pedometers are described as...

• A. Accelerometers measure acceleration, and most also track step count or distance traveled.
• B. Pedometers are worn around the waist or wrist that track step count and distance traveled.
• C. Heart rate monitors measure heart rate.
• D. Journals and fitness logs are used to record daily activity.

Answer: (B)

Pedometers count your steps by sensing body movement. They’re typically worn on the body—around the waist or on the wrist—and they track how many steps you take. Many also estimate distance traveled by combining step count with an assumed stride length. This description matches what a pedometer does, making it the best choice. Other options describe different tools: accelerometers are a broader sensor that measures movement, heart rate monitors track heart rate, and journals/logs record activity without a device.
