Why This Is the Correct Answer
Count the spaces along the run, then include the starting item.
Why the Other Options Are Wrong
Option A: 16 posts
16 posts is below the supported result for guardrail post layout; it likely omits allowance, conversion, coverage, or final round-up.
Option C: 18 posts
18 posts is above the supported result for guardrail post layout; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option D: 19 posts
19 posts is above the supported result for guardrail post layout; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Memory Technique
Guardrail Post Layout cart for Foreman Checks: count first, spaces second, whole the controlling choice last.
