Battery electrolyte is a mixture of water and which of these0 a, Lead sulfateO b. Lead peroxideO c. Sulfuric acidd. Sulfur Dioxide

Option C is correct. Sulfuric acid
Battery electrolytes are liquid electrolytes sometimes called battery acid. These battery electrolytes are commonly found in most car batteries.
This means that when a car battery electrolyte is low, water can be added. This battery electrolyte is formed from a mixture of water and sulfuric acid.
When the battery charges up, some of the water evaporates when the electrolytes heat up.
This sulfuric acid is a very strong acid that ionizes completely to form hydrogen sulphate ions and hydronium ions. This hydrogen sulphate also dissociates in dilute solution to form more sulphate ions and hydronium ions.
