Thank you, that's all the confirmation I needed.
English is not my native language, so I apologize if I sounded rude and I misinterpreted Simon's post.
What do you mean I cannot ask for confirmation? Of course I can. Do you think that if I had notes on this I'd be asking here? After a couple hours of reading on the internet about a topic I'm not very familiar with, I was pretty sure the correct answer is c), but I was hoping someone more...

Thanks for the confirmation.
As I understand the photoelectric effect, one photon transfers all of its energy to an electron, so the energy absorbed by any electron must be the same (for a monochromatic beam), in this case hc/(500 nm) = 2.48 eV. Electrons need at least 2.1 eV to escape this...
