Answer: (d).Because they are more expensive and cause eyestrain and fatigue. Explanation:Random scan displays are typically more expensive than raster scan displays, and they can cause eyestrain and fatigue. Although they can draw lines directly and achieve higher resolutions, the color display using beam penetration technology is generally of poorer quality. Due to these factors, they are used only in niche applications.
