Choose the correct statement regarding the delusion:

The correct answer is Option (1) → Delusion is a false belief held on inadequate grounds

A delusion is a fixed, false belief that an individual holds firmly despite clear evidence to the contrary. These beliefs are not typical of the person's culture or religion and are a key symptom of several psychological disorders, particularly schizophrenia. For example, a person might have a delusion that they are a famous celebrity or that they are being watched by the government.
