解释：

C is correct. Both of Riley’s comments are correct. Electronic algorithmic trading techniques, such as liquidity aggregation and smart order routing, help traders manage the challenges and opportunities presented by fragmentation.

Liquidity aggregators create “super books” that present liquidity across markets for a given instrument. These tools offer global views of market depth (available liquidity) for each instrument regardless of the trading venue that offers the liquidity. Smart order-routing algorithms send orders to the markets that display the best quoted prices and sizes. Additionally, with increasing market fragmentation, traders filling large orders adapt their trading strategies to search for liquidity across multiple venues and across time to control the market impacts of their trades.
