The correct answer is: A. no control.
Limited partners in a partnership business have no control over the management of the business. They are only liable for the amount of money they invested in the partnership. General partners, on the other hand, have full control over the management of the business and are personally liable for the debts of the partnership.
Option B is incorrect because limited partners do not have whole control over the partnership business. Option C is incorrect because limited partners do not have corporate authority. Option D is incorrect because limited partners do not have general authority.
