SOLUTION
To solve this question, we will try and visualize the image and see how many perpendicular lines can pass through point D to line AB.
Please note that perpendicular lines are lines that intersect at a right (90 degrees) angle.
From the above illustration, we see that it is one line (the yellow line) that is possible to be perpendicular from point D to line AB, any other line will not form at angle 90 to line AB.
From the above explanation therefore, we can draw a conclusion that the correct answer is B.
