Answer: Option (3) is the correct answer.
Explanation:
Molecules with different polarity will have different electronegativities and hence, they will have different boiling points.
Therefore, when two different liquids with different boiling points are mixed together then they can be separated by selective boiling and condensation. This process of separation is known as distillation.
A process by which solid particles are separated using a filter paper or filter medium from a fluid (liquid or gas) is known as filtration process.
When bacteria like yeast or microorganisms are used to break down a chemical is known as fermentation process.
When a substance allows the flow of electric current then it is known as conductive substance and the process is known as conductivity.
Hence, we can conclude that distillation is the process that would most effectively separate two liquids with different molecular polarities.
