Solution
The correct option is
A
Solutions, colloids, suspensions
1. Solutions (smallest) have a size < 1 nm.
2. colloids (middle) are between 1-1000 nm.
3. suspensions (biggest size) are > 1000 nm
Therefore, The increasing order for the relative particle size is
solutions ( 0.1 to 1 ) < colloids (1 to 1000 ) < suspensions (more than 1000). The numbers in parenthesis refer to particle size in nm.
