Solution
The correct option is B Exfoliation Exfoliation is a physical weathering process where the outer surface of the rock cracks and peels away layer by layer due to a temperature change. Frost action is a weathering process where water freezes and expands to widen cracks in the rocks. Oxidation and Carbonation are forms of chemical weathering.
