Explanation:

Alzheimer's disease is associated with the depletion of acetylcholine, which is involved in memory and cognitive functions. Mrs. Downing's symptoms (memory issues, disorientation) align with acetylcholine depletion. Dopamine is linked to movement/motivation, GABA to inhibition, and norepinephrine to arousal/stress—none match as closely as acetylcholine for Alzheimer's - related cognitive symptoms.

Answer:

B. Acetylcholine
