Correct answer
C. They keep the windshield clear so you can see hazards in bad weather
Why
Seeing the road is the first safety task, and fogged or dirty glass in rain, snow, or cold weather can blind you within minutes. Working defrosters, wipers, and washers keep your view clear in exactly the conditions where crashes are most likely.
