The correct option is A Private Company
A privately held company, private company, or close corporation is a business company owned either by non-governmental organizations or by a relatively small number of shareholders or company members.Some of the most famous companies in the world are private companies, including Facebook, Ikea, agriculture giant Cargill, and candy maker Mars. Though private companies come in all sizes, a vast majority of private companies are small businesses. If the company is publicly listed, its shares will be listed on the stock exchange and different rules apply to the sale and purchase of the shares. If the company is a private company, the rules about buying and selling shares are set out in the company's constitution and in the COMPANIES ACT 1993.
