Accepted Answer

Option D: 80 degrees F. Entering a standard psychrometric chart with a dry bulb temperature of 90 degrees Fahrenheit and a relative humidity of 65 percent yields an intersecting wet bulb temperature value of approximately 80 degrees Fahrenheit, critical for marine HVAC cooling coil design and load calculations.
