What is the next step in this construction?

Answer:
The correct answer option is B. Construct a line perpendicular to XP through point A.
Step-by-step explanation:
We are given an incomplete figure of construction of a perpendicular line and we are to determine whether which of the given answer options is the next step in the construction.
From the given marks, we can deduce that a perpendicular line to XY is being constructed, passing through P.
So the next step must be to construct a line perpendicular to XP through point A to complete the construction.
The next step in the construction is:
From the given construction we may observe that the construction is of a line segment perpendicular to line segment XY.
The steps of construction are as follows:
1) Take a line segment XY.
2) Take a compass and open the compass more than half the length of XY and then make the arc by keeping the compass one's at X and then at Y.
3) The point where the arc meet draw a straight line such that it pass through the point P.
4) AP will be the perpendicular line to XY and point P is the mid-point of XY.
