Which sieve size is designated as the 75-μm ( #200 ) sieve?

Explanation:
Sieve designations use both the opening size and the mesh number. The #200 sieve corresponds to a nominal opening of about 75 micrometers. So the sieve that is described as 75 μm (#200) is the same, combining both the opening size and its mesh designation. The other options would either give only the opening size, use a much larger opening, or specify a unit that’s far too large for this context.
