Answer
Electricity is conducted in an acidic solution by ions.
Reason — Acids when dissolved in water get ionized into their respective ions.These ions are mobile and allow the solution to carry electric current.
For example :
HCl in water conduct electricity through ions like H⁺ and Cl⁻.
However, in aqueous solutions (like saltwater or acids) or in molten electrolytes (like molten NaCl), electricity is conducted by ions, not electrons. In metals, electricity is conducted by free electrons, not ions. Hence other options cannot be right.
