By design, intersections are risky because vehicles cross one another's paths of travel at various angles. Thus, the correct option is C.
In traffic, intersections may be defined as a point where two or more roads link, split, meet or cross at the exact height, as objected to an interaction, which operates bridges or tunnels to isolate distinct roads.
Intersections are the point of junctions that initiates convergence or divergence of roads at the same height. These are built in order to reduce the effect or load of high traffic in big cities or states.
Therefore, the correct option for this question is C.
