C) The phrase "call your doctor" adds a reference to an esteemed authority D) The phrase -parents of Earth" reminds the audience of the importance of parenting.    

The correct answer is A

Explanation:

The Testimonial Technique is a form of strategy in advertising that features a famous and or authoritative brand recommending vouching for and recommending a product.

This technique relies on the psychology that the target audience would most likely want to relate to the opinion of the super figures endorsing the product. In cases where music stars or football stars are used, their fans who are already evangelists of the star's brand take in on themselves to explore as well as encourage others to purchase whatever product the starts are endorsing in the advert.

The most authoritative brand or person in the poster are the Star Wars Characters. Star Wars movie was released on May 25, 1977, in the USA. It did so well that it grossed a total of $775 Million in sales and was packaged for presentation to a much bigger and wider audience.

Riding on the popularity of the film and its characters, the Ministry of Health released the advert using the characters to draw the attention as well as influence the decision of parents with regard to immunisation.
