A is correct when the electron hits the screen. B is correct when it passes through the slits. It’s both a particle and a wave. The statistical probability of where the electron will be detected is a wave function. The actual detection is a particle function. When the electron is actually detected is a wave function collapse. That’s just a term we call it because no one really knows what the frakk is going on. Excuse my Battlestar Galactica.
Then I would reword your post:
"They're both right at the same time different times/events."
“The actual detection is a particle function. When the electron is actually detected is a wave function collapse.”
The wave function doesn’t collapse. The wave model collapses.”
“That’s just a term we call it because no one really knows what the frakk is going on.”
That is why we have three models!
