The answer is (c.) There is a dense, positively charged mass in the center of an atom
In 1899, Ernest Rutherford, a British physicist conducted a study of the absorption of radioactivity by thin sheets of metal foil. On this experiment, he concluded that all the positive charge and the mass of the atom is concentrated in a small fraction of the total volume of the atom which is called the Nucleus.
