A limited partner's personal liability in a limited partnership is:

A limited partner in a limited partnership has a specific legal status that protects them from personal liability beyond their investment in the partnership. This means that if the partnership incurs debts or faces legal actions, a limited partner cannot be held personally responsible for more than the amount they initially invested into the business. This structure is designed to encourage investment while limiting the risk for those who wish to be passive investors, as opposed to active participants who might face greater liability.

This arrangement contrasts with general partners, who have unlimited liability and are responsible for the partnership's obligations and debts. Thus, the correct choice highlights the fundamental principle of limited liability that is a hallmark of limited partnerships, serving to protect investors while allowing the partnership to operate effectively.
