The term "Fourth Estate" refers to an informal yet significant power in society that is not part of the traditional three branches of government. Among the options provided, the correct answer is option 2: Media. The media is often considered the Fourth Estate because of its role in providing information, analysis, and criticism of the government and other powerful institutions. The media acts as a watchdog, holding those in power accountable for their actions and decisions. Through investigative journalism, the media plays a crucial role in shaping public opinion and ensuring transparency in the functioning of a democracy. While the judiciary (option 1), legislature (option 3), and executive (option 4) are all essential components of government, they do not possess the same level of independent power and influence as the media does as the Fourth Estate.
