The practice that gives minority stockholders a chance to elect at least one director is called:

A) pre-emptive rights of stockholders.
B) maintaining proportionate ownership.
C) voting rights of stockholders.
D) cumulative voting.

Cumulative voting allows minority stockholders to concentrate all of their votes for one director, increasing their chances of being able to elect at least one member to the board of directors. This practice is designed to give minority shareholders a greater voice and representation on the board. Pre-emptive rights of stockholders, maintaining proportionate ownership, and voting rights of stockholders do not specifically address the issue of minority representation on the board of directors.
