In the given figure, \( A B C D \) is a cyclic quadrilateral, \( \angle A B C=70^{\circ}, \overrightarrow{F G} \) bisects \( \angle C F A, \overrightarrow{E G} \)
Qu bisects \( \angle D E B, \angle D C E=60^{\circ} \) and \( \angle E G F=90^{\circ} \). Find \( \angle H E C \).
(a) \( 20^{\circ} \)
(b) \( 40^{\circ} \)
(c) \( 25^{\circ} \)
(d) \( 45^{\circ} \)
