Correct answer
A. As speed increases, the field of view narrows
Explanation
The question is about the influence of speed on the driver's field of view. As speed increases, the field of view narrows - answer A. It does not widen (B) and is not independent of speed (C).
A person standing still takes in about 180 degrees with their eyes. The faster you drive, the more the brain concentrates on a point far ahead of the car, and the image from the sides is no longer registered - at 100 km/h the field of view is only a few dozen degrees, and at very high speeds a narrow "tunnel" remains. A child on the pavement, a cyclist coming out of a side road, a car at the entry to a junction disappear from it, even though they are physically within sight. That is why the Road Traffic Act requires you to drive at a speed that keeps the vehicle under control, adapted to the conditions, and in a built-up area limits it to 50 km/h - at this speed you can still see what is happening on the pavements and shoulders. In town and wherever there are pedestrians, you slow down, move your head and look in the mirrors, not only straight ahead.
