One of the Reasons Personality Disorders Remain Controversial in Clinical

One of the reasons personality disorders remain controversial in clinical practice is that:

A) they appear to be relatively temporary conditions that come and go unpredictably, so they should not be classified as real "disorders"
B) many of the characteristics of each personality disorder are similar, so people can easily be diagnosed with more than one personality disorder at the same time
C) personality disorders appear to have very little in common with normal personality, so calling them "personality" disorders doesn't make sense
D) more than 75 percent of the population could be diagnosed with a personality disorder, which makes the diagnosis meaningless
