The minimum height of the upper rail for barriers on elevated structures for ages 5-12 is 38 inches. Option B, which is 29 inches, is too low and can easily be climbed over by children in this age range. Option C, which is 48 inches, may be too high and may also create a hazard as it may be difficult for some children to see over. Option D, which is 23 inches, is definitely too low and does not provide sufficient protection for children. Therefore, option A is the only suitable minimum height for the upper rail for barriers on elevated structures for ages 5-12.
