The correct response is:
The salt solution is capable of conducting electricity due to the presence of salt ions that facilitate the transmission of electric charge through water.
Reasoning: Salt (sodium chloride, NaCl) dissociates into its constituent ions (Na⁺ and Cl⁻) when dissolved in water, allowing it to conduct electricity. In contrast, sugar (sucrose) and alcohol do not dissociate into ions in solution, so they do not conduct electricity. Therefore, only the salt solution demonstrates electrical conductivity.
