Guards required on decks and balconies must have intermediate rails or ornamental patterns such that a sphere of what MAXIMUM diameter cannot pass through the openings?
a.6 inches
b.5 inches
c.4 3/8 inches
d.4 inches

Guard openings must not allow passage of a 4-inch-diameter sphere, limiting the gap so small children cannot slip through. 6, 5, and 4 3/8 inches all exceed the 4-inch limit and would leave unsafe openings.
