D) physical shortcomings.

Social isolation is the most likely challenge that Martinique will face after losing his wife of forty years. Having been married for such a long time means that his wife played a significant role in his social life and support system. Losing her may leave him feeling lonely and isolated from social activities, which can negatively impact his mental health and well-being. While economic strain, cognitive deterioration, and physical shortcomings are also potential challenges, they are less likely to be the main difficulty that someone in Martinique's situation would face.
