keywords: 

{'carbon dioxide': [2, 0, 5, 6], 'refrigerant': [0, 0, 1, 0], 'lime': [1, 0, 5, 12], 'solid form': [0, 0, 2, 0]}

Option 1 states that carbon dioxide is prepared on a large scale by the action of water on lime. This statement is incorrect. Carbon dioxide is most commonly produced as a byproduct of various industrial processes, such as the combustion of fossil fuels or the fermentation of sugars by yeast.

Option 2 states that carbon dioxide, in its solid form, can be used as a refrigerant. This statement is correct. Solid carbon dioxide, also known as dry ice, has a temperature of -78.5 degrees Celsius and can be used to refrigerate or freeze items during transportation or storage.

Therefore, the correct answer is option 2 - 2 only.
