The correct answer is C. Cumulative preference share.
Cumulative preference shares are a type of preference share that entitles the shareholder to receive any unpaid dividends in arrears before any dividends are paid to ordinary shareholders. This means that if a company does not pay a dividend in one year, the shareholder will still be entitled to that dividend in the following year, and so on.
Residuary preference shares are a type of preference share that ranks below ordinary shares in terms of dividend payments. This means that if a company does not have enough money to pay all of its dividends, the holders of residual preference shares will only receive a dividend after the holders of ordinary shares have been paid.
Convertible preference shares are a type of preference share that can be converted into ordinary shares at a specified price. This gives the shareholder the option to convert their preference shares into ordinary shares if they believe that the ordinary shares are a better investment.
Non-preference shares are a type of share that does not have any preference over ordinary shares. This means that the holders of non-preference shares are not entitled to any dividends until all of the dividends for ordinary shareholders have been paid.
In conclusion, the correct answer is C. Cumulative preference share.
