Solution

The correct option is C Hertz
The photoelectric effect was first observed in 1887 by Heinrich Hertz during experiments with a spark-gap generator. In 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets.
