An electric cell transforms

Concept:

Electric cell: An electric cell has two terminals, a negative terminal and a positive terminal.

• An electrical cell internally converts stored chemical energy into electrical potential energy, allowing a current to flow from the positive terminal round to the negative one via an external circuit.
• Metal cap is positive terminal and metal disc is negative terminal
• There is a potential difference between the terminals of a cell. 

Chemical Energy into Electrical Energy is the correct option.
