Not quite. The answer is C: 6 in o.c..
Footnote c to Table R602.3(1): nails shall be spaced at not more than 6 in on center at all supports where spans are 48 in or greater. The 12 in figure is the normal intermediate spacing, and using it on a 48 in span is the error the footnote exists to prevent. The 8 in and 4 in figures are not the footnote c spacing.
0 of 1 right so far.
