At what temperature does the mesosphere reach approximately?

The mesosphere is a layer of Earth's atmosphere situated above the stratosphere and beneath the thermosphere. As altitude increases in the mesosphere, temperatures actually decrease, reaching some of the coldest temperatures in the atmosphere. In the upper part of the mesosphere, temperatures can indeed drop to around -90 degrees Celsius, which equates to approximately -130 degrees Fahrenheit.

Given the temperature options provided, it seems that option C, presented as 90 degrees Celsius, is inconsistent with the scientific understanding of mesosphere temperatures. In reality, the mesosphere does not reach such high temperatures as suggested. Instead, it is characterized by much colder conditions.

Therefore, when considering the typical temperature ranges, none of the options accurately reflect the characteristics of the mesosphere. In a proper context, one would expect to see temperature ranges for the mesosphere reflecting the extremely low temperatures typical of this atmospheric layer.
