Which of the following is the document provided to shareholders that entitles them to elect directors?

The document that entitles shareholders to elect directors is a proxy. A proxy is essentially an authorization that allows one person to act on behalf of another in voting for directors and other corporate matters. Shareholders use proxies to appoint someone to vote in their stead, especially if they cannot attend the meeting in person. This enables participation in the governance of the corporation, ensuring that shareholders have a say in electing the board of directors.

In contrast, warrants refer to financial instruments that give the holder the right to purchase shares at a specific price within a certain time frame. This does not directly relate to the process of electing directors.

A voting trust is an arrangement in which shareholders transfer their shares to a trustee, who then votes on behalf of the shareholders according to the terms of the trust. While it does involve voting, it is not the direct mechanism through which shareholders elect directors as proxies are.

Preemptive rights give existing shareholders the opportunity to purchase additional shares before the company offers them to new investors, thereby maintaining their proportional ownership in the company. However, like warrants, they do not pertain to the election of directors.

Therefore, the proxy stands out as the appropriate document for shareholders to elect directors.
