What constitutes a quorum for board meetings as defined by the Revised Corporation Code?

A quorum for board meetings, as defined by the Revised Corporation Code, is achieved when a majority of the Board of Directors is present. This means that more than half of the directors serving on the board must be in attendance to legally conduct business and make binding decisions during the meeting. This requirement ensures that decisions reflect a representative consensus of the board, providing legitimacy and accountability for the actions taken.

In contrast, a simple majority of shareholders does not pertain to board meetings but rather shareholders' meetings, where quorum requirements differ. Similarly, two-thirds of the Board of Directors and the presence of all members would also exceed the necessary number for a quorum, which would not align with the flexibility intended by the Revised Corporation Code for corporate governance. Thus, option B accurately reflects the quorum requirements set forth for board meetings.
