Quizplus · Accepted Answer

Falling snowflakes are made of ice crystals, and they will melt if the air temperature is above freezing. Therefore, the air must be unsaturated, with a temperature at or below freezing, in order for the snowflakes to survive. The wet bulb temperature refers to the temperature at which evaporative cooling occurs, and it also needs to be at or below freezing for snowflakes to survive. Thus, choice A is the correct answer.
