Which of the following is responsible to rule out the existence of definite paths or trajectories of electrons

Options

A. Pauli’s exclusion principle.
B. Heisenberg’s uncertainty principle.
C. Hund’s rule of maximum multiplicity.
D. Aufbau principle

Explanation

Heisenberg’s uncertainty principle. Werner Heisenberg, a German physicist in 1927, given uncertainty principle which states that it is not possible to determine simultaneously, the exact position and exact momentum of an electron. The important implications of the Heisenberg uncertainty principle is that it rules out existence of definite paths or trajectories of electrons and other similar particles
