Atomic models were proposed after the discovery of the atom and the sub-atomic particles. Thomson's model of the atom portrayed electrons stuck in the sea of protons. Thus, option C is correct.
J. J. Thomson proposed the model for atoms and their sub-atomic particles called electrons and protons. It was an important model that depicted the presence of the sub-atomic particles in the atom.
According to him, the electron had been known to carry a negative charge that was stuck in the soup or the sea of the positively charged protons. It resembled a plum cake that has electrons stuck in them as the cherries or the plum.
Therefore, the atomic model of the electron stuck in the sea of protons was given by J. J. Thomson.
