Solution
The correct option is A Length Nanometre or nm is a unit of length in the metric system. 1nm=10−9m.
The nanometre is often used to express dimensions on an atomic scale: the diameter of a helium atom, for example, is about 0.1nm, and that of a ribosome is about 20nm. The nanometre is also commonly used to specify the wavelength of electromagnetic radiation near the visible part of the spectrum: visible light ranges from around 400 to 700nm.
