The stratosphere is the layer where temperatures do not fluctuate much, especially in its lower region. While the troposphere is defined by turbulent weather and rapid temperature shifts, the stratosphere remains relatively stable and isothermal near its base. This lack of fluctuation is due to the absence of water vapor and the steady absorption of solar energy. ANSWER: (C) Stratosphere

The stratosphere is known for having a very stable temperature profile, particularly in its lower portion, where conditions are almost isothermal. Unlike the troposphere, which experiences constant thermal changes due to weather and convection, the stratosphere lacks the moisture necessary for such volatility. The temperature actually begins to rise in the upper stratosphere because ozone molecules are absorbing ultraviolet radiation from the sun. This temperature inversion acts as a stabilizer, preventing vertical air mixing. For this reason, the air remains calm and consistent, making it a predictable environment compared to the chaotic and fluctuating air found below.
