The correct options are
A Nirvana can be attained with divine assistance.
B They do not believe in the presence of God.
The term "Hinayana" means the "Lesser Vehicle" of Salvation. It is considered to be the more orthodox school of Buddhism. The Hinayana monks did not believe in the presence of a God and held only the Eightfold path as the means to enlightenment. To them, the Buddha is not a God but an extraordinary human being. They believe that Buddha achieved enlightenment, and thereby the state of Nirvana, through his own efforts.
