Which of the following is not considered a mass level of communication?

The option that is not considered a mass level of communication is conducting method demonstrations with housewives. This form of communication is characterized by its interactive and personalized approach, aimed at a specific audience in a specific context. Method demonstrations involve direct interaction between the demonstrator and participants, allowing for tailored discussions and immediate feedback. This contrasts with mass communication, which is intended to reach large audiences with standardized messages, such as distributing leaflets, broadcasting information via radio, or providing TV plugs. In mass communication, the content is designed to inform or educate without direct engagement or interaction, making method demonstrations a distinct and personalized form of communication.
