Best answer
The correct answer is (b) Sulphuric acid

For explanation I would say: The battery is filled with electrolyte. The electrolyte used in the lead-acid battery is a solution of sulphuric acid. It contains approximately one part of sulphuric acid to two part of water by volume. It should be noted that acid should be added to water and not the vice versa.
