A political party broadcast is considered ad alan

Correct option is B

A political party broadcast is considered a "closed text." In the context of media studies, a closed text refers to a type of media content that is structured to lead the audience to a predetermined conclusion or response. It typically presents a specific viewpoint or argument without leaving much room for interpretation or alternative perspectives. Political party broadcasts are designed this way, with the intention of persuading the audience towards a particular political stance or opinion, leaving little room for open-ended interpretation.
Information booster: In contrast, an "open text" would allow for multiple interpretations and encourage the audience to draw their own conclusions. The terms "Length text" and "Liberal text" are not standard terms used in this context.
