Option 2 : Teacher brings a pond water sample and makes the students observe it under a microscope.

A microorganism, or microbe, is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. An organism that can be seen only through a microscope. Microorganisms include bacteria, protozoa, algae, and fungi. Teacher bringing a pond water sample and making the students observe it under a microscope would be best suited to clarify the misconception as:

Pond water acts as a source of living for many types of microorganisms like bacteria, fungi, and algae.
When the teacher brings the sample of pond water and allows the student to observe it under the microscope the student can easily distinguish different types of microorganisms.
Then it would be realized by the student with proof that the concept he had made was a misconception.
Student himself erases the old wrong concept and builds a new concept.
Pond water is a source of many living microorganisms clears the misconception of children.

Hence teacher bringing a pond water sample and making the students observe it under a microscope would be best suited to clarify the misconception.

On the other hand, a drug, mushroom, and root can't be used as a resource for clearing the misconception of the child because it can't be guaranteed that they may contain a variety of microorganisms like pond water.
