Read the passage below and answer the questions that follow:

Ravi was a sales assistant in an electronics shop who got a commission for every sale over and above his monthly salary. For the past few months, he had been behaving differently, and his performance was declining. When his boss checked with him, Ravi reported that he heard voices in his head telling him that the customers were spying on him. In fact, he was confident that someone had embedded a chip in his brain. Therefore, he was feeling threatened and deliberately victimized. Ravi's colleagues complained that he often used new and strange words and reacted inappropriately in any situation. One of Ravi's neighbours also shared that Ravi loved kicking and hurting street dogs and would laugh loudly when they were wounded and bled. It seemed that Ravi needed to visit a mental health professional to seek help.

In the passage, Ravi's behaviour can be classified under which disorder?

Schizophrenia

The correct answer is Option (1) → Schizophrenia

• Hearing voices in his head → auditory hallucinations.

• Belief that customers were spying on him and a chip was embedded in his brain → delusions of persecution.

• Using new and strange words, reacting inappropriately → disorganized speech and behavior.

• Declining performance at work, social problems → functional impairment.

• Hurting animals and laughing at their pain → inappropriate affect and possible aggression.

These symptoms together are characteristic of Schizophrenia, a disorder marked by hallucinations, delusions, disorganized thinking, and disturbed behavior.
