$\qquad \qquad \bf \huge\star \: \: \large{ \underline{Answer} } \huge \: \: \star$

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
