解释：

C is correct. Liu states that he prefers opportunistic hedge fund strategies that use high leverage, have high liquidity, and exhibit right-tail skewness. The two most common opportunistic hedge fund strategies are global macro and managed futures. Both global macro and managed futures are highly liquid. Further, returns of managed futures strategies typically exhibit positive right-tail skewness in periods of market stress, whereas global macro strategies have delivered similar diversification in such stress periods but with more heterogeneous outcomes. Global macro and managed futures strategies can also use high leverage, either through the use of futures contracts, in which high leverage is embedded, or through the active use of options, which adds natural elements of leverage and positive convexity.
