Final answer:
The description of a patient being completely bedridden, having lost all motor and verbal skills, and being unable to recognize family members suggests that the patient is in the late stage of Alzheimer's disease.
So, the correct answer is: 3) Late stage
Step-by-step explanation:
A patient with Alzheimer's disease who is completely bedridden, has lost all motor and verbal skills, and cannot recognize family members is in the late stage of the disease. In this severe AD stage, patients are often unable to recognize family members or communicate effectively and are fully dependent on others for their care.
These symptoms indicate significant brain damage and loss of function, as the disease has progressed past the early and middle stages, where memory, language, and cognitive deficits are more noticeable but less debilitating.
So, the correct answer is: 3) Late stage
