Final answer:
Continuous care retirement communities are most appealing to couples with financial resources (option B) since they provide a range of services and care levels to accommodate changing needs as residents age, and require a significant financial investment for entrance and ongoing fees.
Step-by-step explanation:
Continuous care retirement communities (CCRCs) are most attractive to couples with financial resources, which corresponds to option B. These communities offer a variety of services and levels of care, from independent living to assisted living and nursing care, all on one campus. They are particularly appealing to those who are planning proactively for their later years and wish to secure their living arrangements while still independent. The combination of housing options, along with social and medical services, allows for a comfortable transition as needs change over time without the need to relocate.
CCRCs require a significant financial investment, including entrance fees and monthly charges, which makes them more accessible to individuals or couples who have planned financially for their retirement. This setup is attractive to those who want to maintain an active lifestyle with the assurance that more comprehensive care is available if needed. It is also a favorable option for couples who may eventually require different levels of care but want to remain close to each other.
