Which of the following is an interactive medium, allowing citizens to send and receive information in real-time?

The Internet is considered an interactive medium because it enables real-time communication and information exchange between users. Unlike static mediums such as television, newspapers, and radio, where content is primarily delivered to the audience without a direct feedback loop, the Internet allows for interaction in multiple forms. Users can send messages, participate in discussions, share content, and engage with others through various platforms such as social media, forums, and email. This two-way communication facilitates a dynamic flow of information, empowering citizens to engage actively rather than just passively consume content.

The other options, while valuable forms of media, do not provide the same level of interactivity. Television broadcasts content that viewers cannot respond to in real-time, newspapers present information in a one-way format, and radio stations predominantly deliver audio content without immediate feedback from listeners. Thus, the Internet stands out clearly as the medium that allows for instantaneous interaction and communication between individuals.
