The correct answer is C. Universal appeal
Explanation:
The universal appeal is a technique for persuasion that relies on ideas, actions, thoughts or experiences all the people or most people know about, share or can identify. In the case of advertisements, this means the product, service or experience promoted can be identified by multiple consumers and buy or use despide of age differences, lifestyle or education level. In the advertisement presented in the photo, the product being advertised are vaccines which are presented by the slogan "Shots aren't just for kids" along with further information about vaccines and a photo of three people of different ages who had been vaccinated. Considering this advertisement aims at showing vaccines are for everyone and not only for kids and inviting all the population to pay or use vaccines this is an example of universal appeal as the information of the advertisement shows the product is for everyone or it is somehow universal.
