There Are Nearly 3 Billion Shares of Facebook Stock

There are nearly 3 billion shares of Facebook stock. Sam, who owns 100 shares of the stock, hopes to raise the market price of the stock by buying another 100 shares. The main reason his endeavor will fail is that

A) he is such a small part of the overall market that his extra demand will have a negligible effect on the market price.
B) Facebook is a monopoly and therefore controls the price of its stock.
C) the Securities and Exchange Commission will intervene if anyone tries to influence stock prices.
D) the other stockholders will attempt to neutralize Sam's efforts.
