What is the typical height range for the Troposphere that is relevant to radar operations?

Explanation:
The Troposphere is the lowest atmospheric layer where weather happens, and its height isn’t fixed—it changes with latitude and season. For radar operations you consider the troposphere as extending from the surface up to about 4 miles at high latitudes to around 11 miles near the equator (roughly 6 to 18 kilometers). This latitudinal variation is why the typical range used is 4–11 miles. The other options point to layers well above the troposphere or only capture a portion of its height, so they don’t reflect how radar signals actually propagate through the lower atmosphere.
