    What is the 'refresh rate' of a monitor, measured in Hertz (Hz)?

    a)
    The number of pixels the monitor can display.
    b)
    The time it takes for a pixel to change from one color to another.
    c)
    The number of times per second the entire screen image is redrawn.
    d)
    The monitor's maximum brightness level.

    Explanation

    A higher refresh rate results in a smoother, less flickering image, which is particularly noticeable in fast-paced video games and scrolling. A standard monitor has a 60Hz refresh rate, while gaming monitors can have rates of 144Hz, 240Hz, or even higher.
