The diagram shows several planes, lines, and points. Vertical plane P intersects horizontal plane R at line f. Vertical plane T intersects horizontal plane R are line g. Line h intersects line f at point B and intersects line g at point A. Line k extends vertically through plane R. Line l extends horizontally through the bottom half of plane P. Point C is on the lower half of the left plane is on line l. Which statement is true about line h?
