Match the List-I and List-II and select the correct answer from the codes given below :

Codes : (a) (b) (c) (d)

Answer: A

The correct matching is (2) (1) (4) (3): hydraulic action - geo, plucking - cirques, deflation - desert pavements, solution - terra rossa.

Hydraulic action of waves forcing water and air into joints in a sea cliff opens a narrow inlet called a geo.
Plucking by glacier ice tears blocks from the back wall of a hollow, deepening it into a cirque.
Deflation by wind removes the fine particles from a desert surface and leaves a lag of stones, the desert pavement.
Solution of limestone leaves its insoluble clay and iron residue as the red soil terra rossa.

Option D swaps deflation and solution, and options B and C pair plucking or hydraulic action with the wrong feature.
