C: The rounding of the pebbles results from weathering and deposition. Explanation: For pebbles to become smooth and rounded, they must experience the processes of weathering and deposition. Weathering involves the breakdown of rocks into smaller materials, creating new sediments, which can occur through chemical reactions or physical means. Deposition happens when eroding agents like wind or water transport sediments from one location to another, reshaping the land. Hence, the smooth shapes of the pebbles stem from the weathering of their parent rocks and subsequent deposition.
