To me, C does not seem to be the best answer. Customers were dissatisfied with the bank's service and so the bank turned to automation. If the customers feel automation is lacking personal touch, there is no way to set it right unlike in the earlier case where the services of the bank can be improved. So it argues against automation.
E though better is still not very forceful. But it is definitely the best of the lot.
