The correct options are
A Oxidation
B Carbonation
C Solution
Oxidation is a process which affects the iron present in rocks. It causes rust on these rocks. Solution is a process where the minerals in the rock get dissolved slowly by the water and form a solution. These dissolved minerals get leached out, leaving behind no residue. Carbonation is the mixing of water with the atmospheric carbon-dioxide, forming carbonic acid. Exfoliation is a physical weathering process.
