单选题 Relative to stock exchanges, OTC stock markets do not: A. trade a higher volume of securities. B. trade a higher market value of securities. C. trade a larger volume of U. S. Government bonds.

【正确答案】 B

【答案解析】OTC markets trade a much larger number of securities than exchanges and, overall, trade a higher volume since 1997. U.S. Government bonds are only traded OTC. Since the largest companies are mostly traded on exchanges, the higher market value is still on the exchanges.
