Final answer:
Freedom of the press is essential for a functioning democracy as it ensures government accountability, informs citizens, and supports the marketplace of ideas. The press serves as a watchdog and a platform for free expression, which enables informed decision-making and active participation in the political process.
Step-by-step explanation:
Freedom of the press is essential for the political system to work primarily because it holds government officials accountable and keeps citizens informed (Option B). In a democracy, the press acts as a watchdog, reporting on government actions and exposing abuses, thereby maintaining transparency and preventing corruption. As Thomas Jefferson noted, a free press ensures a check on government power. The media's reporting also educates the public, enabling them to make informed decisions, crucial for meaningful participation in elections and the political process.
Additionally, the press serves as a platform for citizens to voice their dissent and opinions, contributing to the 'marketplace of ideas' that is vital for a robust self-governing society. Historically, cases like Near v. Minnesota and the Pentagon Papers have underlined the importance of freedom of the press in upholding the right to free expression and preventing government censorship.
While there are certain restrictions to ensure that the media acts in good faith, such as laws against slander and libel, the overall principle of press freedom remains a cornerstone of a functional democracy, facilitating exchange, critique, and innovation in political ideas and practices.
