Correct Option: B Explanation of Why Option B is Correct: Mass media plays a crucial role in shaping public opinion, and option B accurately captures this dual function. Here’s a detailed breakdown of how mass media acts as both a reflection and a shaper of public opinion:

1. Reflection of Public Opinion:
2. Mass media often reports on the prevailing sentiments, beliefs, and attitudes of the public. For instance, news outlets may conduct polls or surveys to gauge public opinion on various issues, such as political candidates, social issues, or economic conditions. This reporting reflects what people are thinking and feeling at a given time.
3. Shaping Public Opinion:
4. Beyond merely reflecting public sentiment, mass media has the power to influence how people think about issues. This influence occurs through:
   • Coverage: The way stories are covered can highlight certain aspects while downplaying others. For example, extensive coverage of a protest can bring attention to a social issue, potentially swaying public opinion in favor of the protestors' cause.
   • Framing: The media can frame issues in specific ways that affect how audiences interpret them. For instance, describing a government policy as a "tax relief" versus a "tax cut" can lead to different public perceptions and reactions.
5. Agenda-Setting:
6. Mass media has the ability to set the public agenda by choosing which stories to highlight. When certain issues receive more coverage, they become more salient in the minds of the public, leading people to prioritize those issues in their own opinions and discussions.
7. Cultivation Theory:
8. This theory suggests that long-term exposure to media content can shape an individual's perceptions of reality. For example, heavy viewers of crime dramas may perceive the world as more dangerous than it actually is, influencing their opinions on crime and safety.

Why the Other Options Are Incorrect: Option A: Mass media solely reflects public opinion without influencing it. - This option is incorrect because it ignores the significant role that mass media plays in shaping opinions. While media does reflect public sentiment, it also actively influences how people think about issues through its coverage and framing. Option C: Mass media is primarily a tool for government propaganda that does not engage with public sentiment. - This option is misleading as it suggests that mass media only serves government interests and does not consider public opinion. While some media outlets may align with government narratives, many independent and critical media sources engage with and reflect public sentiment, providing a platform for diverse viewpoints. Option D: Mass media has no significant impact on public opinion and is often disregarded by the general population. - This option is incorrect because it underestimates the pervasive influence of mass media in modern society. Studies have shown that media consumption significantly affects public opinion, and while some individuals may disregard certain media, the overall impact of mass media on public discourse is substantial. Revision Summary:

• Mass media reflects and shapes public opinion through coverage and framing.
• It sets the public agenda by highlighting specific issues, influencing what people think is important.
• Theories like cultivation theory illustrate how long-term media exposure can alter perceptions of reality.
• Understanding the dual role of mass media is essential for analyzing its impact on society and public opinion.
