However, there are no significant disorganized speech or catatonic behaviors present.

Explanation of each option: • (a) Undifferentiated type – This category includes mixed or unclear symptoms that don’t neatly fit into paranoid, catatonic, or disorganized subtypes. It’s a broader classification used when symptoms overlap. • (b) Paranoid type – Correct. This is the most common subtype, where delusions and hallucinations dominate, but speech and behavior remain relatively intact. Emotional response may appear appropriate, and thought process can seem logical despite strong delusions. • (c) Disorganised type – Includes severe disruption in speech and behavior. The person may show flat or inappropriate affect and illogical thinking, which are absent in the given scenario. • (d) Catatonic type – Marked by disturbances in movement like rigidity, stupor, or excessive motor activity. It may include mutism or negativism, not delusions as the primary symptom.
