Using the available references, if the dry bulb temperature is 55°F (13°C) and the wet bulb is 50°F (10°C), what is the relative humidity?

Correct Answer: Option D — 82%

Cross-referencing psychrometric tables with a dry bulb of 55°F (13°C) and a wet bulb of 50°F (10°C) results in a relative humidity value of 82%, indicating high moisture levels requiring diligent ventilation management.
