- A1Å – 10 nm
- B1 – 100 nm
- C1 – 50 µ
- D1 mm – 10 mm Answers
Explanation
Nanotechnology deals with the study and manipulation of particles and structures at the scale of about 1–100 nanometres. The 1 Å–10 nm range is too narrow, while micrometre and millimetre scales are far larger than the nanoscale. The correct size range is 1–100 nm.
