The production of nuclear energy

Nuclear energy both follows Einstein's mass-energy relation and is not derived from the sun, so both points are true.

The first point holds, as fission converts a tiny mass loss into large energy following E equals m c squared.

The second point holds, as nuclear fuel's energy comes from Earth's radioactive elements, not sunlight.

Because both are true, neither the single choices nor none-of-these fit.

This sets nuclear apart from biomass and fossil fuels, which trace back to solar energy.

A minute fraction of uranium's mass converting to energy can power a reactor for months.
