Step 1: Understanding the Question:
The question presents a behavioral case study of a student named Rajesh who shows complete social isolation, rule disregard, and emotional irritability, and asks us to map this to a specific clinical personality disorder from the Class 12 Employability Skills syllabus.
Step 2: Key Formula or Approach:

- Narcissistic: Characterized by grandiosity, self-importance, and a lack of empathy.
- Dependent: Characterized by clinginess, fear of separation, and a need for excessive reassurance.
Step 3: Detailed Explanation:
