Step 1: Understanding the Concept
Mental disorders are linked with characteristic symptoms.
Step 2: Match each disorder
Amnesia is loss of memory, so A matches IV.
Bulimia is extreme overindulgence of food, so B matches I.
Anorexia nervosa is an emotional aversion to food, so C matches II.
Depression is reduced interest in life, so D matches III.
Step 3: Select the option
This is A-IV, B-I, C-II, D-III, given in option D.
Final Answer:
The correct matching is A-IV, B-I, C-II, D-III.
\[ \boxed{\text{(D) }\text{(A) - (IV), (B) - (I), (C) - (II), (D) - (III)}} \]
