Ray, who is running for public office, seems to be developing a fear of crowds. To which aspect of the definition of abnormality is this example most relevant?

Enochlophobia

Explanation:

Enochlophobia is the fear of crowd. It has no particular illness that might be resulting to it. These category of people find it hard to face crowds, they would rather present before a smaller group than to present to a large number of people. It is recorded that one out of every ten(10) American has this phobia.

Ray has this phobia, and this could lead to limiting him for the office he is running because those running for public offices must know how to face and make presentation to any number of people gathered.
