Solution

The correct option is C The debris the glaciers carry make the existing vallies broader to give them a "U" shape.
Whenever the glaciers move forward, the debris that are trapped in it rubs against the existing valley walls and floor. This leads to the broadening of the valley to give it a "U" shape.
