Solution

The correct option is B Chemical interaction of oxygen carbon-dioxide or water with the rocks
Chemical weathering is a name given to Chemical interaction of oxygen, carbon dioxide or water with the minerals in the rocks. Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid, called carbonic acid, that can dissolve rock.
The correct answer is B.
