Answer:
When forming a solution, the substance which doesn't conduct electricity is B) non-electrolyte.
Step-by-step explanation:
In solutions, non-electrolyte does not separate into ions. It is a bad conductor of electricity. Molecular compounds such as ethanol and sugar are the example of electrolytes. These compounds do not conduct an electric current in either molten state or aqueous solution.
Meanwhile, electrolytes are a good conductor of electricity. There are many electrolytes in our body and they also play a very important role. Some of the electrolytes in our body are magnesium, calcium, potassium, and sodium.
