Colloids have particle size range between
a$10^{-7}$ m to $10^{-10}$ m
b$10^{+7}$ m to $10^{+10}$ m
c$10^{-10}$ m to $10^{-12}$ m
d$10^{-5}$ m to $10^{-7}$ m
eNone of the above / More than one of the above✓ Correct
Explanation
The size range of colloidal particles is approximately $10^{-9}$ m to $10^{-6}$ m. Colloidal particles cannot be seen with the naked eye; they can be seen with the help of a microscope. Colloidal particles can pass through filter paper. Examples of different types of colloids are sol, gel, and aerosol etc.
