Explanation:

The correct answer is A because algorithmic trading necessitates access to low-latency networks, and its widespread adoption has heightened the demand for such networks. Low-latency systems, which operate on networks capable of transmitting high volumes of data with minimal delay, are critical for automated trading applications that rely on real-time prices and market events. In contrast, high-latency systems do not require real-time data processing.

Incorrect Answers:

• B: Markets have actually fragmented into multiple trading destinations, including electronic exchanges, alternative trading systems, and dark pools, rather than consolidating.
• C: While algorithmic trading is used for large institutional orders, it typically involves slicing these orders into smaller pieces and executing them across various trading venues, leading to a decline in average trade sizes.
