Studies of the Relationship Between Dispositional Optimism and Physical/emotional Health

Studies of the relationship between dispositional optimism and physical/emotional health find that compared to pessimism, optimism is associated with

A) less realistic and therefore less adaptive responses to serious emotional and health difficulties.
B) less depression, less distress in the face of serious illness, but no increase in illness recovery or length of life.
C) less depression, less distress in the face of serious illness, faster illness recovery, and a longer life.
D) less distress and depression, but increased risk for serious illness because of a "it won't happen to me attitude."
