Why This Is the Correct Answer

63 work days is above the supported result for concrete sidewalk placement productivity; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option C: 62 work days
62 work days is above the supported result for concrete sidewalk placement productivity; it likely double-counts allowance, uses the wrong unit, or rounds too early.
