Explanation:

The typical size and spacing of joists used over a kitchen can vary based on the building design, local building codes, and the load they are required to carry. None of the options provided (a 2x8 inches, 16 inches on center; b 2x10 inches, 24 inches on center; c 2x6 inches, 12 inches on center; d 2x12 inches, 18 inches on center) directly relates to kitchen joist specifications, as kitchens do not have a unique joist specification compared to other rooms. However, for most residential floors, 2x10 inches joists spaced at 16 inches on center is common. If the question is specifically asking about the conversion of inches to centimeters, then 16 inches on center would be equal to approximately 40.64 centimeters on center.
