Final answer:
Joseph Campbell's monomyth theory, the Hero's Journey, features 17 stages grouped into three main sections: The Departure, The Initiation, and The Return. The provided multiple-choice options do not exactly match the number of stages in Campbell's original monomyth.
Step-by-step explanation:
Joseph Campbell's monomyth theory, often referred to as the Hero's Journey, consists of 17 stages or sub-parts. These stages are generally grouped into three main sections: The Departure, where the hero leaves the ordinary world; The Initiation, where the hero faces trials and gains new knowledge; and The Return, where the hero returns to the ordinary world with newfound wisdom.
However, for the purpose of multiple-choice questions, such as the options provided (A) 5, (B) 7, (C) 12, (D) 3, the answer may be variable as Campbell's original theory does not conform to these numbers, and adaptations and simplifications of his theory might offer a different count.
