The correct option is A. Both statements are individually true, and Statement II is the correct explanation of Statement I.
Statement I is true. Spreading out clothes increases their surface area exposed to the air, which is a common practice to speed up drying.
Statement II is true. Evaporation is a surface phenomenon, where liquid molecules gain enough energy to escape into the gaseous phase from the surface of the liquid. The rate of evaporation is directly proportional to the surface area exposed to the surrounding environment (air). Other factors affecting evaporation rate include temperature, humidity, and wind speed.
By spreading clothes, we maximize the surface area from which water can evaporate, thus increasing the rate of drying. Statement II correctly explains why Statement I is an effective drying method.
