The maximum energy of photo electrons (increases or decreases or remains constant) with increasing frequency and (increases or decreases or remains constant) or with increasing intensity of the light.

Increases,  remain constant

Explanation:

In the light spectrum, the photons with a higher frequency (hence smaller wavelengths) have higher energy. The lower the energy the lower the frequency and longer the wavelengths. The intensity of light does not change the energy levels of these photons. The higher the intensity the higher the density of the photoelectrons.

*tilts head* sounds more like a statement
