B
Firstly latent heat of evaporation can be defined as the amount of heat energy required to evaporate the liquid.
As the liquid evaporates it absorbs heat energy from the surrounding and cools down the surrounding temperature thus producing cooling effect.
1 kg of B requires more heat energy to evaporate than A ( 50 J greater) , meaning it absorbs more heat energy from the surrounding to evaporate. Thus B produces more cooling effect.
Hope this helps.
