{'evaporation increases': [0, 0, 0, 2], 'clothes': [0, 0, 0, 2], 'surface area': [0, 2, 1, 0], 'increase': [3, 1, 10, 35]}

Option 1 states that both statements are individually true and Statement II is the correct explanation of Statement I.

Statement I states that while putting clothes for drying up, we spread them out. This statement is true because when we spread out clothes, it increases their surface area, allowing more air to come in contact with the wet fabric. This increased surface area facilitates faster evaporation.

Statement II states that the rate of evaporation increases with an increase in surface area. This statement is also true because a larger surface area means more molecules of water come in contact with air, increasing the chances of them escaping into the atmosphere as vapor. Therefore, the rate of evaporation will be higher when there is a larger surface area.

Option 1 correctly explains that Statement II is the correct explanation of Statement I. When we spread out clothes, we increase their surface area, which leads to an increased rate of evaporation. Therefore, Option 1 is the correct answer.
