Answer: B, a fusion recrion creates waste material that is easier to store than fission.
Fusion produces far less harmful waste than fission does. The reliance of something independent like whether a reaction will stop on its own when something goes wrong is never indefinite (technological failures are unpredictable and destructive a lot of the time when it comes down to nuclear power).
The change in free energy is obtained from the given parameters after which the value is now applied to obtain the cell potential in volts from the formukar shown in the solution below.
