1. Location identification of a person — Correct. Wearable devices such as smartwatches, fitness bands, and GPS-enabled trackers can identify or transmit a person’s location.

2. Sleep monitoring of a person — Correct. Many wearables track sleep duration and patterns using sensors like accelerometers and heart-rate monitors.

3. Assisting the hearing impaired person — Correct. Wearable hearing aids/cochlear-linked devices and smart assistive wearables help hearing-impaired persons by amplifying or processing sound.

Hence, all three tasks can be accomplished by wearable devices.
