I think in photoelectric emission, the energy of the emitted electrons does not depend on the intensity of the incoming light or the intensity of incident light, but only on the energy (equivalently frequency) of the individual photons. It is an interaction between the incident photon and the outermost electrons.

The kinetic energy of any single emitted electron increases linearly with a frequency above some threshold value and is independent of the light intensity.
(b) The number of electrons emitted per second (i.e The electric current) is independent of frequency and increases linearly with the light intensity.

i=q/t, q=ne so charge q depends on number of electrons and number of electrons depends on intensity. Time t depends on frequency so I guess.
The amount of photoelectric emission current depends on both frequency and intensity of incident radiation.

Frequency alone. Not intensity.
Only classic theory suggested it would be intensity of radiation but einstein said it was because the frequency and hence energy of the photons was more than the threshold.

The maximum kinetic energy of the emitted photoelectrons is independent of the intensity of the incident light but depends only upon the frequency (or wavelength) of the incident light.

In my view, in photo diodes, photon energy is converted into electric energy depends on the intensity of photons. Here the emission is two types, stimulated and spontaneous emission.

By considering the theory of both Classical physics and Quantum physics, the photoelectric emissions current depends on both frequency and intensity of incident light.

Amount of intensity is taken into consideration not frequency because intensity resemble energy how ever speed and no of electrons released is depend on frequency.

How only intensity could result in photoelectric emission when we have e=h*frequency?

Wrong option given actual answer is based on e=hf hence frequency is the answer
