Using the Word Psychosomatic to Describe a Disorder with an Obvious

Using the word psychosomatic to describe a disorder with an obvious physical component is considered misleading because

A) it gives the impression that psychological disorders like anxiety or depression do not have a biological component.
B) it assumes that the physical aspects of a disorder are less important than the psychological aspects.
C) it emphasises the psychological symptoms of a disorder instead of the physical symptoms.
D) it gives the impression that biological disorders are not influenced by psychological factors.
