Explanation:
The larger the surface area of the ice cube the more heat it absorbs, and that's too true that the ice cube generally have the low temperature compared to room temperature and table where's it has been put...
So , I think the correct answer is C Freeze pure water in 3 different-sized ice cube trays, and then place each tray on a different table in the same room.
#The salt water and sugar water makes difference because of the hydrogen bonding whether present or not..so that's why option c seems to be correct...
