All the options provided are correct in the context of guidelines for designing a ribbed slab. Clear spacing between ribs should not exceed 4.5 cm to ensure proper load distribution and structural integrity. The width of the rib should be at least 7.5 cm to provide sufficient structural support. Lastly, the overall depth of the slab should not exceed four times the breadth of the rib to maintain structural efficiency and prevent disproportionate dimensions that could lead to structural weaknesses.
