Final answer:
Arthritis, option d is the one that does not represent an emotional problem affecting driving; it is a physical condition, whereas depression, anger, and preoccupation with problems are emotional issues that can impair driving ability.
Step-by-step explanation:
Of the options listed, arthritis is the one that does not directly represent an emotional problem but is instead a physical condition that may affect the ability to drive. Emotional problems like depression, anger, and preoccupation with problems can all have a significant impact on someone's driving ability because they can impair judgment, lead to distraction, and increase the likelihood of risky behaviors. However, the emotional impact of these conditions can also play a part in heart disease risk, with negative affectivity and depression often being linked to the development of cardiovascular disorders. While arthritis can indeed affect driving by causing pain and restricting movement, it is not an emotional problem.
