Which officer symbol represents the president?

The gavel is widely recognized as a symbol of authority and leadership in parliamentary procedure and meetings, making it an appropriate representation for the president of an organization. In this context, the gavel signifies the president's role in guiding discussions, making decisions, and maintaining order during meetings. This symbol highlights the president's responsibilities in managing the organization and leading its members effectively.

In contrast, while the other symbols may have their own significance, they do not specifically convey the presidential role as clearly as the gavel does. The balanced budget often relates to financial planning, the five-pointed star can represent various values or achievements but is not exclusive to the president, and the pen symbolizes the act of signing documents or legislating rather than the overarching leadership role. Thus, the gavel distinctly aligns with the duties and authority vested in a president.
