Option 4 : 285°

Concept:

Whole circle bearing of any line is its deviation measured in the clockwise direction from the north end reference.

[ alt="F1 N.M. N.J. 19.09.2019 D5" src="//storage.googleapis.com/tb-img/production/19/09/F1_N.M._N.J._19.09.2019_D5.png" style="width: 185px; height: 186px;">

Here 'θ' represents the whole circle bearing of line X - X'.

Important table for conversion of a whole bearing reding to the quadrantal bearing is given below:

Sr No.	Whole Circle Bearing (WCB)	Quadrantal Bearing (QB)	Quadrant
1	0° to 90°	WCB	NE
2	90° to 180°	180° - WCB	SE
3	180° to 270°	WCB – 180°	SW
4	270° - 360°	360° - WCB	NW

Calculation:

WBC = 360 - 75 = 285°
