Answer: b) Axis III
Step-by-step explanation:
Axis III of medical diagnosis displays information about general mental condition that can impact some physical disorder or mental health of the body.
According to the question,Dr.Tings can place this information on Axis III as depression case is related with mental health and Geoff has some severe acne related problem which was physical issue.
