A Correct answer
Explanation

A storage cell (like a lead-acid battery) stores electrical energy as chemical potential, but what it actually stores and delivers is charge. The 'charge' option refers to the separation and accumulation of charge that creates the potential difference. The cell itself is made of lead and other metals, but what's 'stored' is the charge separation.
