That is correct, that is wrong. Trent missed, or left out, one key word - "cable" (as shown in the photo). That is not allowed to be run exposed like that.
2- Is it required for the electrical cable to be in a flex conduit?
Or rigid, or EMT, or IMC, or some approved raceway which is rated to provide protection from physical damage.
3- Do you think steel or galvanized piping is used on water supply. I always find it hard to tell the difference.
Both are shown, what was up above those flexible copper connectors?
4- Water heater is in a closet in the garage. Should it be elevated? I was thinking the lower element could ignite vapors?????
Yes. If the closet floor is elevated, then the ignition source may already be 'elevated' enough.
Also, those flexible copper connectors reduce the size of the pipe, thus they reduce the opening size of the T&P relief valve, thus they are not allowed to be used for T&P relief valve discharge lines.
