Who among the following has no right of ownership to a business organization?

All of the options listed in the question have some form of right of ownership to a business organization, except for the "Debenture holder". A debenture is a type of long-term loan issued by a company that is backed by the company's assets. Debenture holders are creditors of the company and are entitled to receive interest payments on the debenture, but they do not have any ownership stake in the company. Therefore, debenture holders do not have the right to vote on company matters or participate in the company's profits like shareholders, entrepreneurs, partners, or sole-proprietors.
