Name the type of particle has a diameter between 1times 10^-5 m and 2.5times 10^-6 m.

This question asks for the type of subatomic particle that has a diameter between and . The size of subatomic particles is generally several billion times smaller than that. To put this into perspective, the diameter of a typical atomic nucleus (made of protons and neutrons) is about and that of an electron is even smaller. Therefore, the sizes mentioned in the question are much larger than subatomic particles. However, the sizes mentioned more closely align with dust particles, pollen, and red blood cells. Among those options, red blood cells are seemingly in discrepancy, having a size of roughly . Nonetheless, due to smaller divisions present among them, they matches into this classification. Fine dust or pollen are rather larger and exceed the given size. Keep in mind not all dust particles will fall within this range. Only the "coarse dust particles" usually do. Dust specks or particulate matter(),the dimension varies defined most of the time under aerodynamic diameter. Summing up all this, following categorical name has appeared up i.e., inhalable particulate matter or also so-called coarse particulates(by U.S Environmental Protection Agency figures).
