Which of the following is not the duty of a partner of a firm?

Section 9 requires a partner to render true accounts and full information of all things affecting the firm to any partner or his legal representative, so the statement "to render true accounts and full information of all things affecting the firm to any partner but not to his legal heir or legal representative" misstates the duty, whereas "to render true accounts and full information of all things affecting the firm to any partner, his legal heir or legal representative" states it correctly.
