B Correct answer
Explanation

The vertical difference between pole tops is 5m (11m - 6m), and the horizontal distance between their feet is 12m. This forms a right triangle, so the distance between tops equals sqrt(5^2 + 12^2) = sqrt(169) = 13m by Pythagorean theorem. Options A (12m) and C (14m) are incorrect calculations, while D (15m) doesn't match the computed result.
