In the Context of the Double- Slit Experiment, Quantum Uncertainty

In the context of the double- slit experiment, quantum uncertainty refers to

A) our inability to precisely predict the point at which a spread- out matter field or EM field will interact with the screen.
B) the fact that the electron beam or light beam goes through both slits rather than only one.
C) the fact that each interaction with the screen occurs over a broad area of the screen.
D) the fact that the entire matter field or EM field instantaneously collapses to the single interaction point when the field interacts with the screen.
E) the fact that the particles of matter or radiation are instantaneously replaced by a spread- out matter field or EM field when the particles impact the screen.
