Ans is Cup Z, option 4. Metal being a good conductor of heat is able to emit heat very well. When the water is at high temperature, particles have a higher kinetic energy and hence move at a faster speed, resulting in water in a higher temperature to evaporate faster. (Not the full explanation)
There are also other factors affecting rate of evaporation.
