Both A and B are correct.

If the line is along the north direction it is mentioned as N0° or due north.
If the line is along the south direction it is mentioned as S0° or due south.
If the line is along the east direction it is mentioned as N90°E or S90°E or due east.
If the line is along the west direction it is mentioned as N90°W or S90°W or due west.
In ques, it is given 270° means west direction.

Because wcb 270 Means QB is S 90 W.
QB is measured by N and S side. That's N 90 W, and S 90 W.
Than 90 W is common.

Let us assume, WBC=30°, We can say In Reduced bearing is = N 30° E.

Another one assumes WBC=60°, can say in reduced bearing= E 30° N.

So, we can see which quadrant is nearest the angle is first written on a paper then the degree then the direction.

Hence, according to the question, the nearest is exact on W 90°.

Correct @Jayraj.

Because in reduced bearings are done by surveyor compass.

S = 0.
W = 90.
N = 0.
E = 90.
