Which statement is wrong about Bohr's theory

In Bohr's model, an orbit is a fixed circular path, so it is treated as a two-dimensional track on which the electron moves. Bohr also proposed that only certain allowed orbits exist, with quantized energy and angular momentum, and this gives the atom a definite size for a given state. The idea of a three-dimensional region of maximum probability belongs to the modern concept of an orbital, not Bohr's orbit. Therefore the wrong statement about Bohr's theory is the one describing an orbit as a three-dimensional probability region.
