Explanation

To solve this problem, first visualize the standard compass directions: North is at 0 degrees, East at 90, South at 180, and West at 270. South-east is at 135 degrees.

The question states that south-east becomes north. To move from south-east 135 degrees to north 0 or 360 degrees, the map must be rotated 135 degrees counter-clockwise.

Alternatively, you can look at the second condition: north-east becomes west. North-east is at 45 degrees and West is at 270 degrees. This also represents a 135 degree counter-clockwise rotation.

To find what south becomes, apply the same 135 degree counter-clockwise rotation to the original south position 180 degrees. Rotating 135 degrees counter-clockwise from south brings you to 45 degrees on the original compass, which is north-east.

Therefore, south becomes north-east. Correct option is B.
