Answer: (C)

Verified step by step guidance

1. Understand the purpose of a pedometer: A pedometer is a device that counts the number of steps a person takes. It is primarily used to monitor physical activity levels, not to measure calorie intake, heart rate, or directly influence muscle mass.
2. Eliminate incorrect options: The first option about tracking calorie intake is incorrect because pedometers do not measure or track dietary habits. The second option about increasing muscle mass through electrical pulses is also incorrect because pedometers do not emit electrical pulses. The fourth option about measuring heart rate is incorrect because pedometers are not designed to monitor heart rate.
3. Focus on the correct functionality: The primary function of a pedometer is to provide feedback on the number of steps taken daily. This feedback can motivate individuals to set and achieve step goals, thereby promoting a more physically active lifestyle.
4. Relate to behavior change: By providing real-time data on step counts, pedometers encourage users to be more aware of their activity levels and make conscious efforts to increase their physical activity, such as walking more or taking the stairs.
5. Conclude with the correct explanation: The best explanation is that a pedometer provides feedback on daily step counts, which encourages individuals to increase their physical activity and adopt a more active lifestyle.
