Final answer:
An urban man has the highest mortality risk following the death of a spouse due to lack of emotional support and care, alongside the stress of urban living.
Step-by-step explanation:
The individual with the highest mortality risk following the death of a spouse is (c) an urban man. Kate Davidson's study indicated that men experience greater loss after the death of a spouse, as they lack a constant source of care and the focus of their emotional life. In general, urban living conditions can lead to higher death rates due to new diseases compared to rural areas. Hence, an urban man is likely at higher risk of mortality following the loss of a spouse, compounded by the challenges of urban living and potential lack of a support system that a spouse might have provided.Studies have shown that rural men often have fewer social support systems and face greater socioeconomic challenges compared to their urban counterparts, which can contribute to higher mortality rates. Additionally, rural areas may have limited access to healthcare resources, which can further amplify the risk.
