The correct figure is the one in which a long diagonal runs from the top edge down to the bottom-left corner and a shorter parallel diagonal rises from the bottom edge to the middle of the right side.

The question figure has four strokes: a horizontal top stroke, a long slanting stroke from its right end down to the left, a horizontal bottom stroke going right, and from the right end of that bottom stroke a shorter slanting stroke going up to the right, parallel to the first and stopping at about half the height.

In the correct figure, take the left part of the top edge as the top stroke. The diagonal from the top of the right-hand vertical line down to the bottom-left corner is the long slanting stroke, the left part of the bottom edge is the bottom stroke, and the diagonal from the foot of that vertical line up to the middle of the right edge is the shorter parallel stroke.

All four strokes appear there with the same size, direction and joins, so the question figure is embedded in it. In the other figures the long diagonal slants the other way or the parallel short stroke is missing.
