{'limestone': [2, 0, 1, 0], 'sandstone': [1, 0, 0, 1], 'rock type': [0, 0, 0, 1], 'shale': [1, 0, 0, 0], 'calcium carbonate': [0, 0, 1, 4], 'coal': [0, 1, 2, 0], 'sand': [5, 0, 1, 6], 'other organic deposits': [0, 0, 0, 1], 'clay': [2, 0, 1, 7], 'peat': [2, 1, 2, 2], 'rock': [0, 0, 0, 1], 'composition': [0, 0, 0, 1], 'flat flake plates': [0, 0, 0, 1], 'precipitation': [1, 0, 0, 4]}

The correct answer is option 4 (4, 3, 1, 2).

In the given question, we are asked to match the rock types in List-I with their corresponding compositions in List-II.

List-I contains the following rock types: Sandstone, Limestone, Coal, and Shale.

List-II contains the following compositions: Rock formed from peat or other organic deposits, clay breaking easily into flat flake plates, calcium carbonate formed by precipitation, and cemented sand grains.

Now let`s match the rock types with their compositions:

- Sandstone is composed of cemented sand grains, so it matches with composition 4.

- Limestone is composed of calcium carbonate formed by precipitation, so it matches with composition 3.

- Coal is formed from peat or other organic deposits, so it matches with composition 1.

- Shale is composed of clay breaking easily into flat flake plates, so it matches with composition 2.

Therefore, the correct matching is 4, 3, 1, 2.
