Which of the following is a publicly listed company that owns the TSX, TSXV, and the Alpha Exchange?

• A. Instinet Canada Cross Limited
• B. Liquidnet Canada Inc.
• C. TMX Group
• D. Nasdaq CXC Limited

Answer: (C)

The correct answer is TMX Group because it is the organization that operates the Toronto Stock Exchange (TSX), the TSX Venture Exchange (TSXV), and the Alpha Exchange. The TMX Group is a significant player in the Canadian financial markets and is publicly listed, providing various financial services, including the operation of these exchanges which facilitate trading in various securities.

The other options do not fit the description. Instinet Canada Cross Limited, Liquidnet Canada Inc., and Nasdaq CXC Limited are firms that offer trading services and platforms, but they do not own the main Canadian stock exchanges like TMX Group does. Hence, TMX Group is distinct in its ownership of multiple major exchanges in Canada, making it the correct choice.
