What was the major shortcoming in the classical prediction of blackbody radiation that led us to the idea of quantization of light (light treated as particles )? A. Classical theory failed to explain radiations altogether. B. Classical theory failed to explain the absorption of light by any blackbody. C. Classical theory failed to explain the emission of radiation by any blackbody. D. Classical theory failed to explain the experimental results of blackbody radiation and predicted a rapid increase in the intensity with frequency of light causing ultraviolet catastrophe. E. None of the above.
