Which temperature is approximately room temperature?

Room temperature is generally accepted to be around 20°C to 22°C, which converts to approximately 68°F to 72°F. Among the given options, 72°F is the most representative of room temperature. This temperature creates a comfortable indoor environment for most people and aligns closely with standard definitions used in various scientific contexts.

The temperatures that are lower, at 60.5°F and 76.4°F, do not consistently represent typical room temperature; the former is somewhat cool, while the latter is on the warmer side. Meanwhile, 85°F is significantly higher than what is considered comfortable for room temperature and would likely be perceived as warm or hot, depending on individual sensitivity to temperature. Therefore, 72°F best matches the commonly accepted range for room temperature.
