Answer:
B. Biologically aging
Step-by-step explanation:
Agnes is experiencing a decline in age and is therefore not suited to staying alone in a farm even though she was born there and have lived most of her life here. At this point, she needs help and assistance from more physically able people and cannot not afford to stay alone since she may not be able to do everything herself now. A long-term facility in this question would mean an "old people's home" where Agnes would get professional care administered to old people.
