All three of these refer to actual ownership in the underlying company. This gives you the right to vote at meetings, and receive dividends the company pays from time to time.
All equity options have three important characteristics.
Two, each option has an expiry date, after which it becomes worthless if not exercised or sold. And three, each option has an exercise price - the price at which the owner has the right to buy or sell the shares at. Owning an option in a company does not give you any ownership rights to the company itself. You cannot vote at meetings and you do not receive dividends. Each option usually represents 100 shares of the underlying company.
