I gave my students this multiple choice question: In a laboratory procedure, a student observes different sizes of soil particles. Which tool is best for the investigation?

Only one answer is correct among these 4 choices:
- a hand lens with 1X magnification
- a microscope with 40X magnification
- a light microscope with 100X magnification
- a dissecting microscope with 4X magnification

Could you tell me which one is correct?
