The Correct Option is B
Solution and Explanation
A stroboscope emits periodic flashes of light synchronized with moving objects, creating the illusion of a stationary image. This is commonly used in printing and industrial inspections to monitor high-speed machinery. The synchronization of the light with the press speed ensures that the motion of the web or other moving parts appears frozen, which is valuable for inspecting fast-moving materials.
