Bill works at an investment house managing client investments. He notices that John, one of his clients, is always buying stocks that go way up in value but that John atways hoids on to those stocks untit they have lost most of that value, selling at the very end of the cycle and barely making any profit. So Bill decides to sell some stocks of John's one day after they have appreciated drastically in value and then, when the value starts to drop, he uses enough of the money he got from the sale to purchase the same amount of the stocks that John had originally bought. Sure enough, John orders a sale of the stocks just before they reach the original purchase price, Bill sells the stock as ordered and gives John the difference between his sale price and his original purchase price, pocketing the rest. This is an example of which crime $($choose the one that fits best$)$:

A$.$ Fraud

B$.$ Larceny

C$.$ Embeziement
