A Correct answer
Explanation

Runway numbers are based on magnetic heading rounded to the nearest 10 degrees. Runway 9 faces approximately 090° magnetic (east), and Runway 27 faces approximately 270° magnetic (west) - they're the same runway in opposite directions. These are MAGNETIC headings, not true (B, D), and represent 090/270 not 009/027 (C, D).
