A grounded wire is connected to metal appliance cases in order to provide a safe path for electricity to flow in the event of a short circuit or other electrical problem. This helps to protect the appliance and the people using it from potential electrical shocks, and it also helps prevent fires and other accidents.

I'm a bit confused by this question. I know AC is important, but I can't recall the exact applications off the top of my head. I'll have to make an educated guess and select option B.

Okay, let me see. AC is used for things that require alternating current, like electric motors and transformers. I think the two main applications are power and information, so I'll go with option C.
