Solution
The correct option is C HCl
Answer is B.
Ionic solutions have the capability to conduct electricity. Therefore, hydrochloric acid (HCl in solution of water) can conduct electricity because it forms ions.
Though HCl forms covalent bond, it is actually a polar covalent compound. So, when it is added to water, it dissociates into H+ and Cl- ions and thus it can conduct electricity.
In HCl, the H looses its sole electron to form cation. While Cl accepts the electron to form anion. In water it dissociates into ions and so can conduct electricity.
