Final answer:
The correct answer is option D. Tragedy.
Step-by-step explanation:
An Alpha male struggling to fit in is a character archetype that would most likely be found in a work of Tragedy. In tragedies, characters often face ethical choices and suffer downfalls due to their own tragic flaws. According to Aristotle's definition in his Poetics, a tragic hero is a noble character who is mostly good but is doomed to fall because of a personal flaw, experiencing a reversal of fortune (peripeteia), recognition (anagnorisis), and ultimately a catharsis.
The character of an Alpha male may be someone who shows strong impulses and struggles within a significantly challenging environment, which is a common trait in Naturalistic novels. However, these characters usually do not strive to fit in, as they tend to be depicted as unable to change their determined outcome due to their environments or other forces.
While characters in Dystopian fiction, Gothic literature, and Comedy also struggle with various challenges, the specific context of a powerful male character facing significant ethical dilemmas that lead to a personal downfall is most characteristic of the tragedy genre, especially in its classical form.
