The correct answer is: D. delusions
A delusion is a false belief that is not based in reality. It is often a symptom of a mental disorder, such as schizophrenia or bipolar disorder. People with delusions may believe things that are obviously untrue, such as that they are famous or that they are being followed by the government. Delusions can be very distressing and can make it difficult for people to function in everyday life.
Allusions are references to something that is not explicitly stated. They can be to a person, place, event, or work of art. Allusions can be used to add depth and meaning to a text.
Illusions are false perceptions that are caused by the way the brain interprets sensory information. They can be caused by optical illusions, which are tricks of the eye, or by hallucinations, which are false perceptions that are not caused by anything in the environment.
Conclusions are the final results of a process of reasoning. They are based on evidence and can be either true or false.
