An aqueous solution of an acid conducts electricity. This is because

Result
Your answer: —  ·  Correct: A

Explanation

An aqueous solution of an acid conducts electricity due to the presence of charged particles called ions. When an acid is dissolved in water, it undergoes dissociation (ionization), releasing hydrogen ions (H+). These hydrogen ions associate with water molecules to form hydronium ions (H3O+).

The conduction of electricity in a liquid requires the movement of electric charges. In acidic solutions, these free ions act as charge carriers. When a voltage is applied, the ions move towards the electrodes, completing the circuit. Substances like glucose or alcohol do not conduct electricity in aqueous form because they do not dissociate into ions, whereas acids like HCl dissociate into H+ and Cl- ions, enabling conductivity.
