Answer:
D. Melissa is most likely the caregiver because she has the training and personality to do the job better than others in the family.
Step-by-step explanation:
In the given case, Melissa's responsibility and ability to care for her elderly mother is not a result of anything to do with her work and availability. Just because she lives next door to the patient also doesn't seem to the right reason for her to be the sole caretaker.
The statement that her siblings will feel relief and also jealous of her is likely to be true. Moreover, she may also not receive any public help unless something more serious turns up. And also, there is a high chance that Melissa will feel pressured, stressed, and will require help and even have a breakdown.
Thus, the statement that is most likely not true is option D.
