Solution
The correct option is A Both Assertion and Explanation are correct but Reason is not the correct explanation for Assertion.
Studies on black body radiations led to Planck's hypothesis of quantization of electromagnetic radiations.
De Broglie suggested that matter, (like radiations) has dual character. -wave and particle.
Photo-electric effect provides evidence of the particle nature of electromagnetic radiation whereas diffraction provides evidence of its wave nature.
Thus, Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
