Which term describes the density of pixels in an image?

• A. Frame rate
• B. Bit depth
• C. Saturation
• D. Resolution

Answer: (D)

Resolution is the term that describes how many pixels an image contains. It refers to the number of pixels across the width and height, usually written as width × height (for example, 1920 × 1080). More pixels means more detail and a sharper image on a given display. Frame rate is about how many frames appear each second in a video, not pixel density. Bit depth determines color precision per pixel. Saturation is about how vivid the colors are. So, when talking about how densely packed the pixels are in an image, resolution is the best fit.
