Preemptive rights allow a stockholder to:

A) share in profits first.
B) maintain a proportionate ownership interest in the corporation.
C) vote their shares at the annual meeting.
D) dispose or sell their stock without notice.

Preemptive rights enable a shareholder to purchase additional shares in a company before the company offers them to the general public, allowing the shareholder to maintain their proportional ownership in the company. This does not directly relate to sharing in profits first, voting rights, or the ability to sell stock without notice.
