In this question, we are given two lists: List-I and List-II. List-I consists of different types of weathering, and List-II consists of corresponding landforms or processes. We need to match the types of weathering with the correct landform/process and select the appropriate code.

Let`s analyze each option:

Option 1: A-B-C-D

This option states that Chemical weathering (A) is matched with Oxidation (2), Mechanical weathering (B) is matched with Plant roots (3), Glacial deposits (C) is matched with Till (1), and Deposition by ground- (D) is matched with Stalactite (4).

Option 2: A-B-C-D

This option states that Chemical weathering (A) is matched with Oxidation (2), Mechanical weathering (B) is matched with Glacial deposits (1), Plant roots (C) is matched with Till (3), and Deposition by ground- (D) is matched with Stalactite (4).

Option 3: A-B-C-D

This option states that Chemical weathering (A) is matched with Deposition by ground- (4), Mechanical weathering (B) is matched with Glacial deposits (1
