Answer: Option A. Delusion
Explanation:
A delusion is a belief that is clearly false and that indicates an abnormality in the affected person’s content of thought. The key feature of a delusion is the degree to which the person is convinced that the belief is true.
A person with a delusion will hold firmly to the belief regardless of evidence to the contrary. The false belief is not accounted for by the person’s cultural or religious background or his or her level of intelligence.
