Which one of the following is not correctly matched ?

Question

Accepted Answer

Option 3 is the one that is not correctly matched because the Sectoral Model was developed by Homer Hoyt, not Colby.

Here's why the other options *are* correctly matched:

*   **Option 1: Concentric Zone Model - Burgess:** This is correct. Ernest Burgess developed the Concentric Zone Model.

*   **Option 2: Multi Nuclei Model - Harris & Ullman:** This is correct. Chauncy Harris and Edward Ullman developed the Multi Nuclei Model.

*   **Option 4: Rank size Rule - G. K. Zipf:** This is correct. George Kingsley Zipf is credited with the Rank-Size Rule.

Therefore, since the Sectoral Model was created by Hoyt, and not Colby, Option 3 is the incorrectly matched pair.
