What can be the main difference between expression and propaganda in art?

Expression can open questions and experiences while propaganda may impose a one-sided message

The governing concept is the difference between personal or artistic expression and persuasive propaganda. Expression may communicate feelings, experiences, questions, or several possible meanings, so it can invite the viewer to think and respond independently. Propaganda, in contrast, is usually designed to influence attitudes or behaviour toward a particular political, social, or ideological position. Its message is often selective and one-sided, even when it uses attractive images or emotional symbols. Therefore, option A is correct: expression can open discussion, while propaganda may try to direct belief. Options B, C, and D are incorrect because expression and propaganda are not always identical, expression can contain ideas, and propaganda normally has a strong intended message.
