Correct Answer: Sulphuric acid


Solution : The correct option is Sulphuric acid.

Lead-acid batteries contain sulphuric acid. It is essential for the chemical processes within the battery, promoting electron movement and allowing energy storage and discharge. A lead-acid battery's basic design includes lead dioxide (PbO 2 ) as the positive electrode, porous lead (Pb) as the negative electrode and a diluted sulphuric acid (H 2 SO 4 ) solution as the electrolyte.
