Answer:
D. An advertisement depicting a country's leader happily interacting with children.
Explanation:
Propaganda refers to a message that conveys non-critical support of a given political agenda, like the one that a political party and its leader could spouse. In this manner, an advertisement depicting a political leader happily interacting with children conveys a unilateral message in which the leader is shown to be appreciated by society and by children making him or her a relatable character close to the masses.
