Quizplus · Accepted Answer

A) The angular momentum of a particle due to its motion is its orbital angular momentum.
This statement is correct as the angular momentum due to the motion of a particle in its path or orbit is called its orbital angular momentum. 
B) Spin particles with half-integer spin are called fermions.
This statement is correct as per the Pauli Exclusion Principle. Fermions are particles that obey the Pauli exclusion principle and have half-integer spin. 
C) The fundamental unit of angular momentum is h-bar.
This statement is correct. The fundamental unit of angular momentum in quantum mechanics is h-bar (h/2π), which has dimensions of angular momentum. 
D) The units of angular momentum are J·s.
This statement is also true. In SI units, angular momentum is measured in units of kg·m²/s or Joule-seconds (J·s). 
E) Therefore, all of the given statements are true.
