Microscopes working with two lenses show the image of objects magnified by the product of the magnification ratios of the lenses. For example, a microscope with two lenses, one with a magnification ratio of 5 times and the other with a magnification ratio of 20 times, shows the image of the object being examined 100 times larger. An object with size $12.5 \times 10^{-3}$ mm appears how many mm in a microscope with two lenses with magnification ratios of 4 times and 40 times? A) 0.1 B) 0.2 C) 1 D) 2 E) 10
