The correct answer is Lower Troposphere.
Temperature inversion occurs when the temperature increases with increasing height in a layer of the atmosphere, which is the reverse of the normal decrease in temperature with height in the troposphere (lapse rate). Inversions most frequently occur near the Earth’s surface (surface inversions) or at relatively low altitudes, typically within the lower troposphere. These inversions can be caused by radiative cooling of the surface at night, the advection of warm air over a cold surface, or the subsidence of air.
The stratosphere is characterized by a temperature increase with height due to the absorption of ultraviolet radiation by the ozone layer. While this is a normal temperature profile for the stratosphere, the term “temperature inversion” usually refers to a layer within the troposphere or lower atmosphere where the temperature profile is inverted compared to the standard tropospheric lapse rate.
