The correct answer is: A. electronic communication network (ECN).
An electronic communication network (ECN) is a computerized system that allows buyers and sellers to trade securities directly with each other, without the need for a broker. ECNs are regulated by the Securities and Exchange Commission (SEC) and are subject to the same rules and regulations as traditional stock exchanges.
ECNs offer a number of advantages over traditional stock exchanges, including lower trading costs, faster execution times, and greater liquidity. ECNs have become increasingly popular in recent years, and now account for a significant portion of all stock trading in the United States.
