A.
south-west
B.
north-east
C.

D.
north-west
Answer ( Option B)

north-east

Solution

Quadrantal bearing:
* The quadrantal bearing or reduced bearing of a line is the acute angle which the line makes with the meridian. 
* Reduced bearing is measured either from the north end or the south end as the case may be i.e. whichever  is nearer to the line.
* The quadrantal bearing of a line can vary from 0° to 90°.
 
Whole circle bearing:
* In this system, the bearing of the line is measured from the north in a clockwise direction.
* Thus whole circle bearing of a line is the horizontal angle which the line makes with the north end of the reference meridian.
* The whole circle bearing of a line can vary from 0° to 360°.
 
Note:- When a line is in the north-east quadrant, its whole circle bearing and reduced bearing are equal.
