Solution
The correct option is A Neutron
Thomson’s model of an atom describes that the electrons are like seeds in a sphere of positive charge, which is the red edible part of watermelon. Thomson assumed that the negative and positive charges are equal in magnitude, thus the atoms is electrically neutral.
But there is no mention about the neutral particles neutrons in the atomic model of JJ Thomson.
