B) It is a three-dimensional region of space around the nucleus where there is a high probability of finding an electron.

C) It is a rigid physical boundary that prevents electrons from colliding with the positively charged nucleus.

D) It is an exact path determined by measuring both the simultaneous position and linear momentum of an electron.
