Which temperature range is considered room temperature?

Room temperature is generally defined as the range of temperatures that are comfortable for human occupancy and is typically considered to be between 59 to 86 degrees Fahrenheit. This range is often used in various contexts, including pharmaceuticals and laboratory settings, where the storage and stability of products can be significantly affected by temperature.

The range of 59 to 86 degrees Fahrenheit aligns with what is commonly referred to as the ambient temperature in indoor environments. It is important for maintaining the efficacy and safety of medications, as many drugs require storage within this temperature range to remain effective.

Other options either fall below or exceed this range, making them unsuitable for the classification of room temperature. For example, the first option is too low, and the latter two options involve significantly higher temperatures that could affect the physical and chemical properties of substances stored within them. Thus, option B is the correct choice for defining room temperature.
