Estelle has the last i.e., fifth stage of Alzheimer's disease. So, the second option is the correct answer.
Alzheimer's disease is a general term for memory loss and other abilities that are hazardous enough to become a bother in day-to-day life. For those who might think it's like aging, it's not. This is an actual disease in which the person completely becomes unable to function as they did before.
In the earlier stages of Alzheimer's, the patient slowly loses track of their memories, emotions, and other abilities like thinking. As they reach the last stage i.e., the fifth stage, they completely lose the ability to respond and carry on a conversation and it becomes a pain to communicate. Their speech has become aimless and repetitive, they experience more confusion, and they get their words mixed up at times. So, the second option is the answer.
