C Correct answer
Explanation

Refresh rate is the number of times per second a display screen updates its image, measured in Hertz (Hz). A 60Hz monitor refreshes 60 times each second, showing 60 frames per second. Higher refresh rates result in smoother motion and reduced eye fatigue. The 'screen saver' option (A) is unrelated to refresh rate - it's a power-saving feature.
