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.
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.

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°.

Reduced bearing is always from the closest north or south, but in this case, N90W and S90W both are equidistant so option A and B is rejected. When we don't take reference either from north or south, we have to specify W but with W90 is given in option So we go for option C.

The Correct answer is D.
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.
The answer is 90 W.

The answer is 90 W.

The Correct ans is D.
Because 270 means S 270 W.
Because wcb is always respect to N side measure.
The correct format are 90 W.
Because 270 means S 270 W.
Because wcb is always respect to N side measure.
The correct format are 90 W.

I think, options A) &B) is right. I know that in QB system to measure the angle of any line from north meridian and South meridian.

Answer should be (B) because W. C. B is in third quadrant so S 90° W.
