Micro particle

Milli particle

Nano particle

Macro particle

- Nano Particle (Option 3):

- This is the correct answer.

- A nanoparticle has at least one dimension less than 100 nanometres (10^-7 metres).

- These particles exhibit unique properties due to their small size and large surface area relative to volume.

- Micro Particle (Option 1):

- These particles are larger than nanoparticles, typically in the range of 1 micrometre (10^-6 metres) to several micrometres.

- Milli Particle (Option 2):

- This term is not commonly used in scientific contexts for particles and might refer to millimetre scale.

- Macro Particle (Option 4):

- These are large particles usually greater than 100 micrometres and visible to the naked eye.
