Intensity.

Reason: the photoelectric effect requires each photon to have energy >= the material's work function, so it depends on photon energy (E = hf, or equivalently wavelength λ). Intensity only changes the number of photons (and thus the emitted current), not whether a given photon can eject an electron.
