Which of the following is not found in the middle of the compass rose?

The reason "Deviation" is the correct choice is that it represents an adjustment made to account for the difference between true north and magnetic north due to magnetic interference. It is not a fixed or intrinsic part of the compass rose itself, which primarily displays directional information.

In contrast, true north is a fundamental reference point that indicates geographical north and is always represented on a compass rose. Magnetic north is another key element, reflecting the direction that a magnetic compass points, which varies based on local magnetic fields. Cardinal points, which include north, south, east, and west, form the essential structure of the compass rose, marking the main directions. Thus, while deviation is important for navigation and compass accuracy, it does not appear in the center of the compass rose, unlike the other elements mentioned.
