Answer : Option B
The festival is called in Arabic 'Eid milad-un-Nabi'. However, it is to
be emphasized that practicing this festival is not per religion; as the
two festivals after end of Ramadan and that during hajj. Celebrating
prophet Muhammad birthday, although not per religion, but it is not
forbidden. It is considered as good occasion to remind Muslims with the
prophet Muhammad teachings and morals and to renew the intention of
following and adopting prophet Muhammad guides.
