Explanation:

Micron filtration is a process of water clarification in which waste or impure water is passed through a set of sieve which can be of any pore size depending upon the impurity type i.e the size of contaminants or micro organism

However in reverse filtration water is force to passed through a semipermeable membrane on application of pumping force. Distillation is a physical process of cleaning in which mixture is separated based on difference in boiling points and chlorination is addition of chlorine or its compounds.

Thus, option D is correct.
