(单选题)

Which of the following statement is correct according to the context? ( )

A.US market alone amounted to $291 billion last year

B.GBTA stands for travelers’ interest

C.US used to be largest single market in this industry

D.Global business travel is stagnant

参考答案：C

参考解析：

根据文段的第一段，A项错误，不是美国，而是中国达到$291billion，B项正确文段提到现在中国超过了美国，成为了the largest business travel market, 所以昔日是美国。C项GBTA representing the interests of corporate travel managers, 因此C项错误。D项不是stagnant(停滞，不景气)，反而会有发展。所以答案选C。
