In `angle ABC`, AB and AC are produced to points D and E respectively. If the bisector of `angle CBD` and `angle BCE` meet at a point O and `angle BOC=57^@`, then `angle A` is equal to :
त्रिभुज ABC में, AB और AC क्रमशः D और E तक बढ़ाये जाते हैं। यदि कोण `angle CBD` और `angle BCE` के सम द्विभाजक बिंदु O पर मिलते हैं, और `angle BOC=57^@` तो `angle A` बराबर है

A

`114^@`

B

`66^@`

C

`57^@`

D
