What Is It? #2

A more appropriate title would be "How big is it?" because I'm going to tell you what it is, and you have to guess the size. These are the holes or "nozzles" from the business end of a typical inkjet printer cartridge. You need to correctly guess the approximate diameter of the nozzles:

A. 1 millimeter

B. 0.1 millimeter (100 micrometers)

C. 0.03 millimeter (30 micrometers)

D. 0.007 millimeter (7 micrometers)

E. 0.00001 millimeter (0.01 micrometers or 10 nanometers)
