The position and velocity of the electrons in the orbit cannot be determined simultaneously

(D) The correct answer is $(D)$.Bohr's model assumes that electrons move in well-defined circular orbits with definite radii and velocities.Statement $(D)$ describes Heisenberg's uncertainty principle,which states that it is impossible to determine simultaneously the exact position and exact momentum of an electron.This principle contradicts the Bohr model's assumption of defined orbits.
