Best answer
Correct answer is (a) Virtual reality display

The best explanation: Virtual reality displays are for future virtual cockpits where the image is directly projected onto the retina of the pilot by a raster scanned laser light beam. The current technology of implementing a virtual retinal display involves lasers, optical fibers and miniature vibrating mirrors for raster scanning the retina of the eye, together with coupling optics.
