• Hypodermic Needle (Magic Bullet) Theory of Communication:
• Formulated in the 1920s–1930s (Harold Lasswell) to explain mass propaganda:
• Statement (I) is correct: The model is universally known interchangeably as the Magic Bullet Theory or the Hypodermic Needle Model.
• Statement (II) is incorrect: The theory conceptualizes that mass media messages are injected directly, instantly, and uniformly into a passive, defenseless audience, exerting direct and immediate powerful effects, rather than indirect effects. (Indirect, multi-step effects were later proposed by Paul Lazarsfeld's Two-Step Flow Theory).
• Conclusion: Statement (I) is correct but Statement (II) is incorrect, making Option 3 correct.
