Solution
The correct option is B Carbonation Carbonation is the mixing of water with the atmospheric carbon-dioxide to form carbonic acid. Rainwater reacts with carbon dioxide in the atmosphere to form carbonic acid. This reacts with calcium carbonate present in rocks like limestone to form a solution. This solution acts on rocks continuously to form weathered material.
