Answer

Answer:

C. water refreezing in the rock crevasses

Brief Explanations:

Water - ice cycle is a common physical weathering. When water in rock crevasses freezes, it expands, exerting pressure on the rock and causing it to break apart. Abrasion (A) is also physical weathering but not the best - fit here. Gravity (B) is related to mass movement rather than typical physical weathering for rock - breaking.
