Solution
Niels Bohr made a significant contribution to atomic theory. His contribution is best described by option C. He made a model of the atom, with electrons circling the nucleus. This model, known as the Bohr Model, proposed that electrons move in fixed orbital shells around the nucleus and that the energy of an electron in an atom is quantized, meaning it can exist at certain energy levels but not between them. This model helped to explain how atoms interact with light and laid the groundwork for quantum mechanics.
