Step-by-step explanation:

D) A prism is a transparent, geometric, optical object with a minimum of two polished plane faces inclined relative to each other, from which light is reflected or refracted. ... They are used to redirect light at a designated angle. They have the capacity to reverse the direction of light by internal reflection

B) Slow down!

Reduce your speed before approaching a curve. Watch out for road signs warning of approaching curves so that you have ample time to slow down before steering through the curve. It is advisable to drive below the posted speed limit as you approach and drive through curves. Never ignore curvy road signs.
