C should probably be play on, but depending on the wording of the rule in the particular ruleset you are using (you didn't say which) regarding detached equipment, I can see some umpires awarding bases here.

I wouldn't. I believe that the INTENT of the detached equipment it to prevent INTENTIONAL striking of the ball with said equipment, and in this case, it's the ball striking the equipment, and no intent exists.

I expect some here may disagree. I would probably rule play on.

Agree with all answers, except I can't imagine anyone awarding bases for the C situation.
