Correct Answer
Explanation
The correct option is (d) because wearable technology integrates various sensors into portable devices to perform diverse functions, such as smartwatches using GPS for location tracking, fitness bands monitoring sleep cycles, and smart hearing aids assisting the hearing impaired. Option (b) is the most tempting wrong choice if one narrowly defines wearables as only fitness trackers, overlooking that modern hearing aids are a sophisticated category of wearable medical devices. The core concept being tested is the broad range of practical and medical applications of sensor-based wearable electronics.
