Final answer:
The characteristics mentioned describe Avoidant Personality Disorder. It is a condition that causes significant social inhibition, feelings of inadequacy, and a heightened fear of negative evaluation, affecting interpersonal interactions and self-perception.
Step-by-step explanation:
A pervasive pattern of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation is most characteristic of Avoidant Personality Disorder (B). This mental health condition involves extreme sensitivity to what others think about them, leading to social inhibition and a reluctance to engage in social situations for fear of being embarrassed, criticized, or rejected. Individuals with Avoidant Personality Disorder often perceive themselves as socially inept, personally unappealing, or inferior to others, which significantly impacts their ability to interact with others and form relationships.
