Bolts should protrude a minimum of 2 threads beyond the end of the nut in playground equipment for safety reasons. Not protruding at all (option A) could result in the nut coming loose and causing the equipment to collapse. Option C (1 inch) is not specific enough as it can vary depending on the size and type of nut and bolt used. Option D (4 threads) is not ideal as it is too far beyond the nut and can increase the risk of injury due to a longer exposed bolt. Overall, B is the most appropriate and commonly recommended option for protrusion length.
