Debenture holders of a company are its creditors.

Debentures are a form of long-term debt instrument issued by companies to borrow money from the public or institutional investors. When individuals or entities purchase debentures, they become creditors of the company. Debenture holders lend money to the company and are entitled to receive regular interest payments and the repayment of the principal amount at maturity.

Shareholders, on the other hand, are the owners of a company who hold shares or equity in the company. They have an ownership stake in the company and are entitled to share in the company`s profits through dividends and capital appreciation.

Debtors are individuals or entities who owe money to a company, whereas directors are individuals appointed to manage and oversee the operations of the company.

Therefore, the correct answer is: Debenture holders are the creditors of a company.
