What happens in Alzheimer's disease when the hippocampus experiences altered neurogenesis and brain functioning declines?

A) disruption in messages sent from one neuron to the other, resulting in confusion and disorientation
B) generation and development of new neurons is impaired resulting in an inability to replace dead neurons
C) prefrontal cortex compensates for loss of neuronal activity resulting in little loss in problem-solving but a greater decline in memory
D) interference in signals sent to muscles resulting in jerky, uncontrollable movements
