Final answer:
Wanda is engaging in Emotion-focused coping to handle the stress caused by being unfairly blamed at her software firm.
Step-by-step explanation:
When Wanda works at a software firm and was unfairly blamed by her boss for the new program being behind schedule, she experienced stress and later decided to go for a long run to manage her response to this situation. The category of coping in which Wanda is engaging in is D) Emotion-focused coping. Emotion-focused coping consists of efforts to change or reduce the negative emotions associated with stress, such as anger in Wanda's case. Since the situation with her boss and the schedule delay is perceived as something out of her control, Wanda is using running as a way to cope with the emotions elicited by that stress rather than trying to address the problem directly.
