In `triangle ABC` ,`angle A=52^@`and O is the orthocentre of the triangle (BO and CO meet AC and AB at E and F respectively when produced). If the bisectors of `angle OBC` and `angle OCB` meet at P, then the measure of `angle BPC` is:
त्रिभुज ABC में, `angle A=52^@` है तथा O त्रिभुज का लम्ब केंद्र है | (BO और CO बढाए जाने पर AC तथा AB से क्रमशः E तथा F पर मिलते हैं |) यदि `angle OBC` तथा `angle OCB` के समद्विभाजक P पर मिलते हैं, तो `angle BPC` का मान क्या होगा ?

A

`138^@`

B

`124^@`

C

`132^@`

D

`154^@`
