I’m pretty confident that if the button isn’t set up properly, it won’t respond when clicked, so I lean towards option C.

I feel like if the button isn't found, it just won't show up in the layout, which sounds like option B.

I remember a similar question where not finding a component caused the app to not respond. So, maybe option C could be correct?

I think if we don't initialize the button, it might lead to a crash when clicked, but I'm not entirely sure.
