The ability to image accurately.

• A. Clarity
• B. Resolution
• C. Contrast
• D. Brightness

Answer: (B)

Focus on resolution—the ability to distinguish fine details in an image. When resolution is high, small features are separated cleanly, so the resulting image accurately represents the scene. Clarity relates to perceptual sharpness but can be affected by blur and noise and doesn’t quantify how small a detail can be resolved. Contrast is about how much difference there is between neighboring tones, which helps edges stand out but doesn't define the smallest resolvable feature. Brightness is simply the overall light level; it affects visibility but not the capacity to resolve fine details. So the term that best describes imaging accurately is resolution.
