Correct option is D)

Solutions of acids and bases produce some ions that can carry electric current, so they are said to be electrolytes.
Acids contain at least one hydrogen atom that can be removed when the acid is dissolved in water. An acid is a substance that produces hydrogen ions in a water solution. When an acid dissolves in water, hydrogen ions interact with water to form hydronium ions.
The strength of an acid or base depends on how many acid or base particles dissociate into ions in water. When a strong acid dissolves in water all molecules ionize into ions. When a weak acid dissolves in water a small fraction dissolve in water.
