The maximum energy of the electrons released in a photo cell is independent of

Explanation

The correct answer is Option B: intensity of incident light. The maximum energy of the electrons emitted from a photoelectric cell is determined by the frequency of the incident light, as expressed in Einstein's photoelectric equation. The energy of the emitted electrons increases with the frequency of the light, but not with its intensity. Intensity affects the number of electrons emitted (the current), but it does not change the energy of individual electrons. Option A is incorrect because the frequency is directly related to the maximum energy. Option C is incorrect as it includes Option A, and Option D is incorrect because the correct answer is indeed present. Thus, understanding the distinction between frequency and intensity is key to solving this question.
