C 10780, 2074/
D 10256, 2074/
AI Explanation

The correct answer is A) 10256, 2023/. The air temperature groups are encoded using the dry bulb and wet bulb temperature readings. In this case, the dry bulb temperature is 78°F and the wet bulb temperature is 75°F. To encode these values, the first two digits (10) indicate the dry bulb temperature in whole degrees Celsius, which is 26°C. The next three digits (256) indicate the wet bulb temperature in tenths of a degree Celsius, which is 25.6°C. The final two digits (23) indicate the date in the month, which is the 23rd. The other options are incorrect because they do not accurately represent the given dry bulb and wet bulb temperature readings.
