Explanation
Choice A is correct. It’s given that 
. Solving this formula for H expresses the relative humidity in terms of the temperature and the dew point. Subtracting T from both sides of this equation yields 
. Multiplying both sides by 
yields 
. Subtracting 100 from both sides yields 
. Multiplying both sides by 
results in the formula 
.
Choices B, C, and D are incorrect and may result from errors made when rewriting the given formula.
