Assertion :Classical Physics deals mainly with macroscopic phenomena and includes subjects like Mechanics, Electrodynamics, Optics and Thermodynamics. Reason: Classical physics is inadequate to handle microscopic domain and Quantum Theory is currently accepted as the proper framework for explaining microscopic phenomena as it deals with the constitution and structure of matter at the minute scales of atoms and nuclei.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
