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 uncertianity principle
C. Hund's rule of maximum multiplicity
D. Aufbau principle

Explanation

Werner Heisenberg , a German physicist in 1927, stated uncertainly principal which states that it is im possible to determine simultaneously, the exact position and exact momentum of an electron.
Mathematically, `Deltax xx Deltarhoge=(h)/(4pi)`
The important implications of the Heisenberg uncertainly principle is that it rules out existence of definite parth or trajectroeis os electrons and other similar particles.
