Final answer:
Personality disorders differ from other kinds of disorders in their complex interplay between genetics, biological factors, and environmental influences, with behaviors that typically manifest before adulthood and persist over time.
Step-by-step explanation:
The development of personality disorders is considered to differentiate from other disorders due to their complex interplay between genetic, biological, and environmental factors. Unlike other mental disorders, personality disorders are characterized by an enduring pattern of behavior and inner experience that deviates markedly from the expectations of the individual's culture. Personality disorders usually begin in late childhood or adolescence and continue into adulthood, reflecting a persistent, rather than an episodic, nature of symptoms.
In terms of the correct response, none of the given options accurately describe how the development of personality disorders differ from other mental disorders. While genetics and early experiences certainly play a role in the development of personality disorders, they are not exclusively determined by genetic factors (Option A), nor do they solely have a stronger biological basis (Option B). Personality disorders do typically manifest before adulthood (Option C), but they are indeed manifested and potentially exacerbated by a person's early experiences (contrary to what's expressed in Option D).
