Which type of wiring method is resistant to water exposure?

The selected answer is accurate because Type MC (Metal Clad) cable is specifically designed to offer protection against water exposure. This type of cable consists of conductors which are enclosed in an interlocking metal armor, providing a barrier that is not only durable but also resistant to moisture. Therefore, it can be used in various environments, including those where water exposure is a concern.

On the other hand, Type NM cable, commonly known as non-metallic sheathed cable, is not suitable for wet locations. It has a plastic sheath that can degrade when exposed to moisture. Type UF cable, while rated for underground use and therefore resistant to moisture, is generally more suited for direct burial applications and does not have the same level of physical protection as MC cable. Type SE cable is mainly used for service entrance applications and typically requires additional protection against the elements if installed outside.

Overall, Type MC cable stands out as the most suitable choice in terms of resilience to water exposure due to its robust design and protective features.
