The correct answer is B) 15 knots. The illustration D049NG shows a surface analysis chart, which displays wind speed and direction information. At position A, the chart indicates a wind speed of 15 knots, as shown by the wind barb symbol. This is the only wind speed value that matches the answer choices provided. The other answer choices are incorrect because they do not match the wind speed reported at position A on the surface analysis chart. Option A (10 knots) and option C (20 knots) are not the correct wind speed, while option D (25 knots) is also not the wind speed shown at the specified location.
