The correct answer is C. publicly held stock.
Publicly held stock is stock that is owned by the general public, as opposed to being owned by a single individual or a small group of individuals. Publicly held stock is typically traded on a stock exchange, such as the New York Stock Exchange or the NASDAQ.
Privately held stock is stock that is not owned by the general public. It is typically owned by a single individual or a small group of individuals. Privately held stock is not traded on a stock exchange.
Self-held stock is stock that is owned by the company itself. It is not traded on a stock exchange.
Enactive held stock is not a real type of stock. It is a made-up word.
I hope this helps!
