Answer: C. High beam; safety belt
Explanation: the high beam symbol comes on when the driver activates the high beam mode of headlights. The high beam is employed in order to see farther and sufficiently than what the low beam would provide. It's usually employed when there are no oncoming vehicles and outside of urban areas.
The safety belt warning light is a reminder for vehicle occupants to put on their safety belts. It remains on for as long as it remains unfastened with the engine on. It sometimes comes with accompanying audio notes depending on the car type.
