Controlling smart devices at home demonstrates which role of technology?

Correct answer: Remote monitoring and control

The governing concept is connected technology, in which devices exchange data through a network and respond to authorized commands. A smart light, camera, thermostat or appliance may be monitored or controlled using a phone or another connected interface. Hence, option A is correct. Option B describes manual rather than smart control; C contradicts network communication, and D does not explain how connected devices operate.
