What type of meeting is necessary for the Board of Supervisors (BOS) to conduct official acts?

The Board of Supervisors (BOS) is required to conduct official acts during either a regular meeting or a specially convened session. Regular meetings are established sessions scheduled to discuss and make decisions on governance, whereas specially convened sessions are called to address specific issues that cannot wait until the next regular meeting. These meetings provide a formal framework for decision-making, ensuring transparency and adherence to governance protocols.

The other options do not fulfill the requirements for official actions. A virtual meeting might serve as a format for communication, but without being a properly scheduled session, it cannot be classified as an official act. A closed session is designed for confidential discussions, typically regarding sensitive matters, but it is not a general setting for conducting the official business of the Board. An informal gathering lacks the procedural structure necessary for the Board to enact official policies or decisions. Therefore, the need for either a regular meeting or a specially convened session makes option A the correct choice.
