A

The motion of the electrons in Rutherford model was unstable because, according to classical mechanics and electromagnetic theory, any charged particle moving on a curved path emits electromagnetic radiation; thus the electrons would lose energy and spiral into nucleus. To remedy the stability problem, Bohr modified the Rutherford model by requiring that the electrons move in a orbit of fixed size and energy. The energy of an electrons depends on the size if the orbit and is lower for smaller orbits. Radiation can occur only when the electrons jumps from one orbit to another. The atom will be completely stable in the state with the smallest orbit. Since there is not orbit of lower energy into which the electron can jump.
