Answer:
A. The media shape public opinion by choosing how to report on
developments and policies.
Step-by-step explanation:
The media has a lot of influence in the U.S. political process. Every outlet of media chooses which stories to report, which policies to highlight, and more importantly, the kind of angle, spin, or bias, from which to report.
Audiences are likely to shape their views according to the way the Media reports, making them very influential in shaping the political opinions of the audience.
