Answer:
C) The mirror allows the light to be reflected so the objects behind the car can be seen.
Explanation:
Every driver needs to know or see what's behind them especially for security purposes and this is one of the purposes a rear view mirror serves.
The mirror also helps to reduce glare reaching a driver's eyes as the angle can be adjusted depending on the time of the day but most especially at night as other drivers behind would have their head lights on.
Adjusting the rear view mirror helps to reduce the glare so that the driver can see what's behind without being affected by excessive glare.
