J J Thomson Model could not able to explain the following?

J.J. Thomson's model (plum pudding model) proposed a sphere of positive charge with embedded electrons, which could explain electrical neutrality. However, classical electrodynamics predicted that accelerating electrons would radiate energy and spiral into the nucleus, making the atom unstable. Thus, the model failed to explain the stability of the atom. It also did not account for the nucleus, so it could not explain nuclear stability, but electrical neutrality was explained. Therefore, the model could not explain stability of atom, making option A correct.
