The correct answer is
E: Hellman arrived in California in 1859 and worked as a clerk in his cousin’s dry goods store. He eventually opened his own store, where as a courtesy he would store his customers’ valuables in the store safe. One customer who kept gold in the safe would often come in while drunk and withdraw some of his gold. At one point, this customer went to retrieve some of the gold when he was sober, and upon discovering much of the gold gone, he wrongly accused Hellman of theft and attacked him. Hellman realized that this informal storage system was not a good idea, so he printed business cards reading “I.W. Hellman, Banker” and began providing deposit books to customers.
