The production and type of charge of a body are primarily determined by the presence of electrons. When there is a deficiency or surplus of electrons, it results in the body having a net positive or negative charge, respectively. Protons and neutrons contribute to the mass of the body but do not directly determine its charge.
thus making option A correct
