Final answer:
The critical component in deciding the optimal housing arrangement for older persons is their specific needs, level of independence, and ability to maintain a good quality of life.
Step-by-step explanation:
The critical component in deciding the optimal housing arrangement for an older person is their specific needs and level of independence. Factors such as physical and mental well-being, social support, and access to care should be considered.
For example, if an older person requires daily assistance with activities of daily living, assisted living or a nursing home may be more suitable. On the other hand, if they are relatively independent and prefer living in a community with other older adults, cluster housing or independent living options may be ideal.
Ultimately, the decision should be based on the individual's preferences, level of care needed, and their ability to maintain a good quality of life.
