Correct answer: chemical to electrical.
A coal-fired plant converts the chemical energy stored in coal into heat by combustion, that heat produces high-pressure steam (thermal energy), the steam turns a turbine (mechanical energy), and the turbine drives a generator that produces electrical energy. The "radiant to nuclear" option is incorrect — the plant does not use nuclear energy, and radiation is not the primary energy form being converted.
