The correct answer is C. sensors.
Smart fitness clothing is clothing that is embedded with sensors that can track the wearer’s activity, such as heart rate, steps taken, and calories burned. The sensors can then transmit this data to a smartphone or other device, where it can be used to track progress and motivate the wearer to stay active.
Batteries are also commonly used in smart fitness clothing, as they provide the power to run the sensors. Bluetooth is another common feature, as it allows the sensors to communicate with a smartphone or other device. However, the sensors are the most important component of smart fitness clothing, as they are what collect the data that is used to track the wearer’s activity.
Internet connectivity is not essential for smart fitness clothing, as the sensors can store data locally and then be synced with a smartphone or other device when the wearer is in range of a wireless network. However, internet connectivity can allow the wearer to view their data in real time and share it with others.
In conclusion, the correct answer is C. sensors. Sensors are the most important component of smart fitness clothing, as they are what collect the data that is used to track the wearer’s activity.
