The correct answer is B. glacial erosion.

To arrive at this answer, we can follow a few steps:

1. Understand what a U-shaped valley is: A U-shaped valley is a type of landform that is carved out by a glacier. It is characterized by steep, straight sides and a wide, flat bottom.

2. Consider the processes that can create this landform:
- Coastal erosion (option A) refers to the wearing away of coastal land by the action of waves and currents. It typically creates features like cliffs, sea caves, and arches, but not U-shaped valleys.
- Deposition (option C) is the process of sediment being dropped or deposited by wind, water, or ice. While it can create various landforms, it does not produce U-shaped valleys.
- Wind erosion (option D) occurs when wind carries and deposits sediment. However, it is not responsible for shaping U-shaped valleys.

3. Focus on glacial erosion (option B): Glacial erosion is caused by moving glaciers that scrape and carve away the land underneath them. As glaciers flow downhill, they have immense power to pluck and erode rocks, creating U-shaped valleys. This process involves the combined forces of abrasion (rock-on-rock scraping) and plucking (the dragging away of loosened rock material).

Based on this analysis, the correct answer is B. glacial erosion, as U-shaped valleys are a well-known result of this process.
