Concept:Rutherford's atomic model fails because it treats the revolving electron as a classical charged particle that must radiate energy.
Explanation:According to classical physics, an electron revolving around the nucleus should radiate energy.
If the electron radiates energy continuously, it loses speed and spirals into the nucleus.
This would make the atom unstable, which is not observed in reality.
Continuous radiation would also give a continuous spectrum, not the line spectrum seen in experiments.
These are the main limitations of Rutherford's model.
So, the limitations are correctly stated in (I) and (II).
Answer:C. I & II only
