The correct answer is; low
For scanning a slide, low power is usually used.
Low power scan is a scan that is done at 10X magnification to view the location of cells, or organisms. When a slide is viewed with low power, about 360 – 400 images can be contained in an entire slide with each image containing about 930 microns in the vertical direction, and about 695 microns in the horizontal direction. Low power is usually used for scanning a slide in order to view the content of the slide very clearly without missing any cell. The lower the magnification, the higher the view.
