Potential energy is energy that an object has to because it is likely to soon move(something that is still at the top of a ramp has potential energy).
Kinetic energy is energy that an object has due to motion (something that is rolling down a hill has kinetic energy).
Radiant energy is energy from electromagnetic waves, such as the energy from the sun. So since this question asks about the sun, we know radiant energy is either the input or the result. Since we are going from sunlight energy to energy in the form of food, we know we are starting with radiant energy.
It could be B but i'm not sure...
