Best answer
The correct choice is (b) False

Easiest explanation: No, this is a false statement. The photoelectric effect cannot be explained by wave theory because, in the photoelectric effect, the electron emissions are immediate without a time delay, whereas in wave theory, the electrons are emitted only after a small instant of time.
