A Correct answer
Explanation

For a flag staff with angle of elevation 30° from a point 200 meters away, use the tangent formula: tan(30°) = height/200. Since tan(30°) = 1/√3, the height = 200 × (1/√3) = 200/√3 ≈ 115.47 meters. Option A (115.47 meter) is correct. The other options don't match this calculation.
