    Dear student, the figure isn't showing the location of point X, Y and Z. The black region the figure has subdued the location of point X, Y and Z. However for your reference I am answering this question. Limestone will be metamorphosed from Granitic intrusion and will form marble Shale will be metamorphosed from Granitic intrusion and will form Hornfels Sandstone will be metamorphosed from Granitic intrusion and will form quartzite Now, if you will know the exact location of point X, Y and Z (which is not visible in figure); you can depict the metamorphosed rock type and match them accordingly. For any confusion, feel free to ask.
