In this system, energy from the cyclist is converted to a lot of energy and a little bit of energy. The energy from the turning bicycle wheel spins the turbine which generates energy. The fluorescent light bulb converts this energy into two new forms: a lot of energy and very little energy.

the answer would be 32*f

i had the same answer and put c. deflect randomly in multiple directions.   i looked it up on google and what i found was this;

scattering of light: by small particles and molecules in the atmosphere. different from reflection, where radiation is deflected in one direction, some particles and molecules found in the atmosphere have the ability to scatter solar radiation in all directions.

i know it's kinda annoying when you are just given a google article but this is why i think it is c.   i will try to let you know if i got it right.
