Which temperature corresponds to the range for room temperature?

Room temperature is typically defined as the range in which most indoor environments are comfortable for human occupants, which generally falls between approximately 15 to 30 degrees Celsius. This range allows for a suitable balance of warmth without causing discomfort due to excessive heat or cold.

When considering the other options, the second choice indicates extreme cold temperatures that would not be conducive to a comfortable indoor setting, thus falling far outside the definition of room temperature. The third and fourth choices present temperatures that are significantly warmer or colder than what is typically experienced indoors. Specifically, the Fahrenheit ranges provided in those options correspond to conditions that would more likely be found in outdoor environments rather than the comfortable, controlled temperatures within a room.

In summary, the correct answer highlights the standard expectation for room temperature, anchored in a common range that promotes comfort and usability in everyday settings.
