The Correct Option is A
Solution and Explanation
Step 1: Persistent delusional disorder is a psychotic condition in which one or more non-bizarre, fixed false beliefs persist for at least 1 to 3 months, with relatively well-preserved functioning and no prominent hallucinations.
Step 2: Among the recognised subtypes, the persecutory (paranoid) type is the most common. Here the patient firmly believes that they are being conspired against, cheated, spied on, followed, poisoned, or otherwise harassed.
Step 3: The other options are valid but rarer subtypes. Somatic delusion involves a false belief about bodily function or a physical defect, the jealous type involves a fixed belief that the partner is unfaithful, and the grandiose type involves an inflated belief about one's own worth, power, or identity. None of these is as frequent as the persecutory type.
Step 4: Therefore the most common type of persistent delusional disorder is the delusion of persecution.
