Options

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