Identifying the odd term out in a complex numerical series

Trace the directional headings sequentially:

From a Southward heading (180^\circ), the person executes a 225^\circ clockwise rotation. Clockwise movements add directly to the angular heading: New Heading = 180^\circ + 225^\circ = 405^\circ.

Normalize the angle by subtracting a full circle (360^\circ): 405^\circ - 360^\circ = 45^\circ. An angle of 45^\circ on a standard standard compass grid points exactly to North-East.

Answer: (d).
