What is one requirement for the media to function effectively in a democratic society?

In a democratic society, one of the fundamental requirements for the media to function effectively is providing unrestricted access to political information. This ensures that citizens are informed about governmental actions, political processes, and various viewpoints. Access to comprehensive information allows individuals to make educated decisions, engage in discussions, and participate in the democratic process fully. When the media presents a wide range of information and perspectives, it fosters transparency and accountability, which are crucial for a healthy democracy.

The other options diverge from this principle. Promoting a single viewpoint restricts the diversity of opinion necessary for informed debate. Concealing information undermines the public's ability to hold power accountable and engage with issues that affect their lives. Limiting citizen access to journalists diminishes the flow of information available to the public, which is essential for an effective democratic dialogue.
