The correct answer is C.
Obsessive compulsive disorder is a mental health condition where someone feels compelled beyond rationality to repeat the same action over and over until they feel that they have done it correctly or it no longer needs to be done. In the example shown Susan arranges her kitchen dishes 10 times a day everyday, over and over. This is OCD. The other two are eating disorders with the first being Anorexia and the second is Bulimia.
