In a cyclic quadrilateral $ABCD$ , if side $AB$ is extended to a point so that an exterior angle is formed, then $\angle DBC$ (i.e. the exterior angle equivalent here) equals—

a $\angle ADC$
b $\angle ABC$
c $\angle BCD$

ব্যাখ্যা

In a cyclic quadrilateral, an exterior angle equals the interior opposite angle. Hence the exterior angle at $B$ equals $\angle ADC$ , the angle opposite to it.
