Final answer:
Vic's resolution arises from introspection in the dark theater, leading to the understanding that he will pursue acting no matter the outcome of the interview.
Step-by-step explanation:
In the passage provided, Vic's conflict is resolved through a profound personal realization shaped by the setting of the shadowy theater. The description that best captures how this setting contributes to the resolution of Vic's internal conflict is 'C. Sitting alone in the dark theater causes Vic to think about his problem more clearly.' This moment of solitude amidst the thinning crowd allows Vic to contemplate his devotion to acting and accept that his journey will continue regardless of the outcome. The environment of the theater, with its rich history and connection to countless performances, bolsters Vic's resolve. The shadows growing deeper as candidates are called in and the sensation of being left virtually alone in such a meaningful space create an atmosphere conducive to introspection, eventually leading to Vic's epiphany.
