This one is extremely easy. I am positive the answer is C.
Answer:
Garmin watch
Explanation:
I have been wearing my Garmin smart watch pretty much non-stop for the past two years. I utilize it to track my daily activities (steps, heart rate, calories) and also my physical activities (running, lifting, etc). Garmin sends all of this info to an app that allows me to track my daily activities on a daily, weekly, monthly, and yearly basis so I can really get a grasp on how I am progressing/digressing physically. It makes it much easier to track my goals and shows me what I need to work on.
The answer here is option (D). Any of the above for an extended period of time
