Where is the water shut-off valve located in the AFT galley?

The water shut-off valve in the AFT galley is located below the boilers at floor level. This positioning ensures that the valve is accessible for maintenance and operational needs while remaining out of the way to avoid interference with other activities in the galley area. The placement below the boilers helps minimize the risk of accidental adjustment by crew members during regular operations, as it is not located at heights where incidental contact can easily occur.

Other options may suggest alternative locations, but they don't align with the standard design practices found in aircraft galleys. For instance, having the shut-off valve at eye level or in the overhead panel would potentially complicate access or increase the risk of accidental manipulation, while a location near the refrigerator would not provide the necessary proximity to the source of water use, which in this case relates to the boilers. Hence, option B accurately reflects the correct placement of the shut-off valve within the galley environment.
