According to given figure,

Angle 11, Angle 20 and Angle 16 forms angles of a triangle,

so, by angle sum property of a triangle :


\qquad❖ \: \sf \: \angle11 + \angle20 + \angle16 = 180 \degree


\qquad❖ \: \sf \: \angle11 +66 + 43 = 180 \degree


\qquad❖ \: \sf \: \angle11 +109 = 180 \degree


\qquad❖ \: \sf \: \angle11 = 180 \degree - 109


\qquad❖ \: \sf \: \angle11 =71 \degree


\qquad \large \sf {Conclusion} :

  • Option B is correct
