JEE Main 2021 Physics question

In a photoelectric experiment, increasing the intensity of incident light :

• (A)increases the number of photons incident and also increases the K.E. of the ejected electrons
• (B)increases the frequency of photons incident and increases the K.E. of the ejected electrons.
• (C)increases the frequency of photons incident and the K.E. of the ejected electrons remains unchanged
• (D)increases the number of photons incident and the K.E. of the ejected electrons remains unchangedCorrect
