A62 degrees F
B63 degrees F
C77 degrees F
D80 degrees F
AI Explanation
The correct answer is D) 80 degrees F. To determine the wet bulb temperature, we need to use the dry bulb temperature (90 degrees F) and the relative humidity (65%) provided in the question. By using a psychrometric chart or a wet bulb temperature calculator, the wet bulb temperature can be determined to be 80 degrees F for the given conditions. The other options are incorrect because they do not accurately reflect the wet bulb temperature for the given dry bulb temperature and relative humidity. Option A (62 degrees F) and Option B (63 degrees F) are too low, while Option C (77 degrees F) is too low compared to the correct answer of 80 degrees F.
