The correct statement is the fourth one. The riverbed erodes into a V-shaped valley while the glacier erodes into a U-shaped valley. Glaciers and rivers have tributaries or small rivers that join the main river. For glaciers, as it erodes deeper, the small river is left higher up the steep sides. For rivers, as it erodes, ridges of land form in its upper course.
