{'frost action': [0, 0, 0, 1], 'freezethaw action': [0, 0, 0, 1], 'crystallization': [0, 0, 0, 7], 'mechanical weathering': [1, 0, 0, 4], 'hydration': [0, 0, 1, 0]}

The correct answer is option 4: 1, 2, and 3.

Let`s dissect each option one by one:

Option 1: "1 and 2 only"

- Statement 1: Crystallization is a form of mechanical weathering. This statement is correct. Crystallization occurs when water seeps into cracks and crevices in rocks, and when it freezes and expands, it exerts pressure on the surrounding rock, leading to mechanical weathering.

- Statement 2: Hydration causes granular disintegration. This statement is also correct. Hydration refers to the absorption of water by minerals in rocks. When minerals absorb water, they may expand and cause the rock to disintegrate.

Option 2: "2 and 3 only"

- Statement 2: Same as above, this statement is correct.

- Statement 3: Frost action is synonymous with freeze-thaw action. This statement is also correct. Frost action refers to the process where water freezes and expands within cracks, causing the rocks to fragment. It is also commonly referred to as freeze-thaw action.

Option 3: "1 and 3 only"

- Statement 1: Same as in option 1, this statement is correct.
