I believe the answer is a nanometer (which can measure wavelengths and such)
So B!

Answer:
The blacktop, which is used on the asphalt driveways are mainly formed of the sand, rock, the cement made up of asphalt, and a petroleum product that has a tar-like appearance. The base of the driveway is formed of a four to eight-inch layer of solid filled with granules. The base is further covered by a two or three inches hot and fresh asphalt, which with the assistance of a heavy machine gets compacted briskly.
The influence of the solar radiation is different on a shoveled asphalt driveway and a snow-covered asphalt driveway. The particles present within the shoveled asphalt driveway captivates the radiation due to which it turns hot. On the other hand, the radiation gets reflected into space by the snow-covered asphalt driveway as the snow on the top is white and smooth.
The number of chromosomes
<span>Electron microscopes therefore allow for the visualization of structures that would normally be not visible by optical microscopy. Light microscopes are not able to see things in a larger magnification compared to electron microscopes. Also you're able to see in 3d in electron microscopes and you can't see in 3dimentsional in light microscopes.
