Answer:
(D). Peripheral route persuasion
Step-by-step explanation:
Peripheral route persuasion occurs when a listener or recipient of a message accepts the message because of other characteristics added to the message (such as background music or catchy images), and not based on the main content of the message itself.
Therefore a strategy that associates pictures of a candidate with emotion-evoking music and images, to build political support, illustrates the peripheral route persuasion.
