Answer: Option (D) is the correct answer.
Step-by-step explanation:
When a substance dissolved in water dissociates into ions then the resulting solution is known as an electrolyte.
As electric current is the flow of electric charges therefore, a solution or substance having ions is able to conduct electric current.
Whereas a solution which does not contain any ions is known as a non-electrolyte.
A saturate is a solution which contains maximum amount of solute. A saturated solution is also able to conduct electricity. Similarly, a dissociate will lead to the formation of ions into a solution.
Hence, a dissociate is also able to conduct electric current.
Thus, we can conclude that a compound that does NOT conduct an electric current in aqueous solution is known as a non-electrolyte.
