Which statement about 4K UHD resolution relative to HD is correct?

Explanation:
Resolution is about how many pixels make up each frame. HD ( Full HD ) is 1920 by 1080 pixels. 4K UHD doubles both dimensions to 3840 by 2160. When you double the width and the height, the total pixel count goes up by 2 x 2, which is four times as many pixels. So 4K UHD has four times the resolution of HD. It isn’t eight times, it isn’t the same, and it isn’t half.
