The temperature in tropopause would be the least at the
-
Equator
-
Poles
-
Mid lattitudes
-
All the above
A
Correct answer
Explanation
Since the tropopause is at the highest altitude above the equator (due to strong tropical convection) and the troposphere cools with increasing altitude, the tropopause temperature is lowest at the equator. This can reach -80°C or lower compared to around -60°C at the poles.
