Planes A and B intersect.
Vertical plane B intersects horizontal plane A. Point W is on the line where the planes intersect. Vertical line m is on the left half of plane A. Horizontal line n intersects line m at point X and line k at point W. Line l is on the lower half of plane B with point Y.
Which describes the intersection of plane A and line m?
line k
line n
point X
point W
